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 -- and having heard from the kernel people about this
for several years, I think it might be -- it's probably something we
should do anyway.
It would also remove things like OLPC XO-1 (no idea whether it would
impact the VIA processor in the 1.5) which in some communities use
newer releases but would never ever hit the update servers.
