I think you missed the part of the thread where I mentioned how the current behaviour was necessary.
Installing and *enabling* extensions by default in Fedora, and deviating from upstream isn't something we'd consider.
I thought FESCO had made it clear that desktop SIG does not have
full control over the defaults
( which is why I went ahead and created Gnome SIG as in so it could
be as upstream wanted it to be heck we could even default to btrfs
and disable lvm and all the other generic useless stuff
rsyslog,sendmail,cron etc we ship and enable by default )
