I thought about it, and I lean toward dropping i686 completely. The only
thing that SSE2 requirement will do is even further decrease of i686 users.

Because we will deprecate i686 eventually, I don't think we should beat
around the bush. There is no benefit of switching to i786 in terms of
time spent for building packages. Even our completely old pkgstats data
say that 8.53% use 32 bit Arch, while only 4.21% of submissions came
from systems with amd64-incompatible CPU. It's just not worth the hassle.
