It would be nice to have some actual real-world benchmarks that show that this
change actually buys something. Recompiling a kernel isn't too high of a
barrier to entry, but recompiling userland is a bit much. Many moons ago we
decided to not remove 80386 support from 5.x, and since we've already
branched RELENG_5 I think we are pretty much stuck with that now. 6.0 won't
be that long in coming and we can kill it for good there.
