Pardon me if i mistake here, a _non_ lawyer point of view:
Here arised in my mind that epsg tables ar not similar as PCI ID plain only database, a new entry in that database need certain certification and probaly very precise technical mesurments before it can be validated and ratified. I dont think anyone can easy do this step, like just PCI-ID ones. EPSG asummed this task to collect cand ertificate those constants and projections in the past. The process is not an easy one as far I understanded, but this is only the technical side. That could be olso the strong reason to not let those constants to be altered in some way.
Please correct me if i mistakenly miss understood that EPSGactivity from tech point of view. Just wanted make some comment over certain value of database.
I think that there are several good parallels here, the most obvious seems to be that of the GNU Free Documentation License (GFDL), specifically section 4, which permits modification, but also describes what you must do as the end result of modification.
Another good example is the Bitstream Font License. Bitstream wanted to make their Fonts available for the Free Software community, and to permit people to make derived fonts from Bitstream fonts, but they didn't want people selling the fonts standalone, or referring to any derived fonts as "Bitstream".
Here is their license, in its entirety:

======================
So, to sum it up, here's what we would like to see:
The license needs to permit people to create derived works of the EPSG dataset. Simply because we cannot fathom any possible derived works does not mean that the right should be withheld. This is at the very heart of open source and free software. However, it is perfectly acceptable to say that those derived works may not call themselves the EPSG dataset.
If we can get that, we can include the EPSG dataset in Fedora. :)

Yes I agree. Understood here.
However to be bad a bit, i really look forward for someone who can invent a new projection for his own pospose :-) Maybe. It will be never used by no one, not even for survey the back yard garden :) Maybe bottom of my aquarium ? it wouldn be serious one at all. But than, e.g if i invent one wich i think fit perfect for some land i will look forward anyway for someone's help to certificate at all it, since i will not be able to claim it is functional and better and more precise than i dont know wich one particulary. And if its about certificate it probably i go EPSG to help me out. Maybe its similar with encryption algorithms, where olso is pretty difficult to come out these days with a new one, and claim its performance and usability in some ways. I still can use my early high scool one invented "reverse mixing of ABC letters" TM at all, but probably just for send out mail to my girlfriend :-D
Just my +.5 cent opinion, i still think here is very low interest to alter EPSG and make derivative work out of it. It see total nonsense in real world.
If we can get that, we can include the EPSG dataset in Fedora. :)
Would be great !

A projection would be an application of the data, not a modification of this data.
And the EPSG data aren't the holy grail either, there is more precise data available (non-free). Consider you being a company or some entity that wants to refine the data for a certain part of the world, you wouldn't have the right to do so.
I can think of tons of applications that would require changing/refining the data. Even for changing the format and base coordination system to adapt to computations for a given problem, which semantically would not modify the data, but technically it does and could be violating the license again (I haven't read the license, just infering from what this thread is discussing).
But than, e.g if i invent one wich i think fit perfect for some land i will look forward anyway for someone's help to certificate at all it, since i will not be able to claim it is functional and better and more precise than i dont know wich one particulary. And if its about certificate it probably i go EPSG to help me out.
Or maybe a competing entity that will have emerged. And with a non-free dataset you would be bound to the rights holder.
