I agree that the proposal is now a lot clearer and I certainly see
how it furthers the first goral of seeing how Fedora trunk comes
together asn an EL build, modulo one concern below.
I don't understand how it helps evaluate something like a new
higher CPU baseline - nobody disputes that packages can be built
to a new baseline which is what this would prove. The argument
is about the effect on consumers of such a baseline and about
what proportion of users/machines would be cut off from further
upgrades and this proposal does nothing to help with that.
As to what proportion of users/machines would be cut off, we don't
care about the exact number. It was already established that the
number is an unacceptable amount. The real question is, how much of a
performance advantage do modern machines get from running things built
for such a baseline. If there is a significant advantage, then it
becomes worthwhile to explore methods to make relevant packages built
to such a baseline available in standard Fedora. There have been
various ideas on how to make them available without making them a
required minimum, but all of them involve a non-trivial amount of
work. It would be a waste of time and energy if the real world
advantage turns out to be minimal.
