That means even more of the bureaucracy that people are so quick to
disparage here...

That isn't always obvious to the packager of some piece of infrastructure.
Change GCC, the "normal" applications continue compiling fine (or get fixed
as part of the update in the distributin), but some strange package
somewhere was relying on a GCC bug (or misfeature, or sloppiness) and blows
up when you try to build it. Has happened dozens of times to me, and I'm
still grateful GCC moves forward and becomes more standards-conforming.

That is done, albeit imperfectly. It usually gets caught and fixed quickly.

That is impossible, and besides the point anyway: Part of the benefit of
being part of the distribution is the previous point.

New upstream versions... go talk to them ;-)

It is fast /because/ it integrates upstream changes as early as
possible. Can't have fast advances and no change at the same time.

OK. Leave out the kernel, ...

Choose something else and leave us in peace then.

Some people do so even if you don't understand them. That would mean your
understanding of what and why people do as they do is flawed, not
(necessarily) said developers.

[A standard is developed by consensus among people trying various
 non-standard approaches on what the best way to do something is. This
 means exploring non-standard approaches (even ones going against said
 standards at times).]

LSB and similar standards mean aiming at the lowest common denominator.
I.e., it might work just fine, but it will certainly waste much of what
Fedora (or any other particular distribution) is all about

I'm using Fedora rawhide daily. Our labs (several hundred users) are
running latest Fedora most of the time (except when the releases fall at
awkward times in our terms).
