No, that is exactly my point.  Back then the griping by affected
active users happened in more or less real time compared to the
changes being done.  Now fedora goes off on its own merry way for
years before its breakage comes back to haunt the people that wanted
stability.

Don't think people running a bunch of RH5 servers really cared about X
or desktops at all...

That one was sort of inevitable.   Likewise for grub2 and UEFI...

Well, that was the equivalent of fedora.  You don't use that in
production.   The x.2 release mapped pretty well to 'enterprise''  -
except maybe for 8.x and 9 which never really were very good.

In these observations you have to take into account just how badly
broken the base code was back then.  Wade through some old changelogs
if you disagree.  There were real reasons that things had to change.
But by, say, CentOS5 or so we had systems that would run indefinitely
we a few security updates now and then.  (Actually CentOS3 was pretty
solid, but you have to follow the kernel).

I'm never against adding new options and features.  But I am very
aware of the cost of not making the new version backwards compatible
with anything the old version would have handled.  And I'm rarely
convinced that someone who doesn't consider backwards compatibility as
a first priority is going to do so later either, so you are likely
wasting your time learning to work with today's version since
tomorrows will break what you just did.

Yes, but on the other hand, people still pay large sums of money for
other operating systems.  And there are some reasons for that.
