Not sure I understand this. You want to raise armhf to ARMv8? Why would
anyone then install a 32-bit port when they could just use the 64-bit
port in the first place?

What's the advantage of requiring ARMv8CRC?

Isn't that something that should be done using hwcaps support?

POWER8 already has AltiVec. For powerpc and ppc64, AltiVec is not
required in the baseline because there are some embedded systems
that people use that don't support AltiVec despite being more recent
than some of the first AltiVec CPUs.
