Good question. I think it would be more productive to think in percentages
instead of raw numbers, in this case. There are a lot of FOSS projects out
there that would love to have 12k users. :)

Certainly, I would consider 10% a healthy number when talking about portion
of user base. I would even argue that 1% is still a healthy number,
particularly with regard to decisions that have a reasonable chance of
disenfranchising those affected. While I hate seeing people leave a
community, I wouldn't be able to defend 0.1%. So, somewhere in there is my
general boundary.

Now cost changes all of that, of course. Obviously if 75% of our effort is
going to please 10%, then 10% isn't a healthy number.

Clearly effort is going into enabling Fedora to work on non-SSE2 systems by
teams invested in the success of Fedora in general and not the success of
non-SSE2 systems in particular. I just don't know how to quantify it.

Based on Smooge's awesome numbers, it looks like x86_32 is in the 2.3%
range. It would be interesting to see how this stacks up to AArch64 and
other secondary arches. Unfortunately, what complicates things is how
x86_32 is so intertwined with x86_64.

To your point re: a remix, that is an option we've discussed within the SIG
and is one we are open to exploring. A remix wouldn't resolve issues
introduced by enabling SSE2 by default, unless we maintained a parallel set
of packages e.g. i586 (which I've already been warned about. :) )

Yes, I would agree :)
