I ran into this unannounced change:

If this is accepted, all x86 hardware on which Fedora can run will
support SSE2, and we should reflect that in the i686 build flags.
How likely is it that this proposal is accepted? Ideally, we would know
this before the mass rebuild so that we can change the compiler flags in
redhat-rpm-config.
Currently i686 users are at about 1/6th of x86_64 users, by mirror
checkins. I don't have an easy way of knowing how many of those i686
checkins are old releases -- I'll need to ask Smooge to make a custom
report -- but I think it's fair to guess that it's significantly tilted
that way. So, taking a SWAG, I'd say maybe 10% of our users would be
impacted. That's pretty big, but on the other hand if the cost is
disproportionate If cost is an issue, consider to drop all these ppc, arm, s370 and mips
targets.
Their user base is like magnitudes smaller than the i686 user base,
while these target are having a significant impact (and thus cost) on
everything in Fedora.
