NetBSD supports non-x86 pretty well. You can't say that ARM, MIPS, or
PowerPC are x86 clones.
Old slow machines have their uses in NetBSD and among them are finding
unscaleable algorithms. Speed can hide a multitude of sins and one of
the easiest way to expose is to see how NetBSD runs on a slow machine.
The older machines also help us to think outside of our comfort zone
and that is useful.
Even if it might appear so, there has been no decision to drop older
platforms so everyone calm down and take a breath.
