Rich.
I hate this argument.
The "experience and knowledge" claim applies to everything we could possibly change.
Change.\nIs.\nGoing.\nTo.\nHappen.
That's a too black-and-white view. Of course there is and will be change - what would we all be doing here if there were nothing to change, after all? The thing that needs to be appreciate is that every change has _costs_ on the user-base.
[...]
So, yes, change is going to happen, and some change is clearly good. But when there are 10 programmers on a project and 100,000 users, each change has to be _very obviously_ good, or it might be better avoided.
Especially minor changes that don't bring any measurable benefit (perhaps making the system "cleaner" or making programmer's life more convenient) but require time from each user to adapt are better abandoned than implemented.
Looking at real costs and benefits is the right approach. But do not overlook potential benefits of making it practical to add features that will help the sysadmins or avoiding a security issue later that the sysadmins would otherwise have to scramble to fix (maybe not applicable to /dev/shm, but in general).
