I concur that armv[67] is the closest thing we have to a second tier 1. arm64 is also quite good, but still has a few more rough edges compared to armv[67]. > Now it'll never happen, because there seems to be > growing momentum to throw everything 32-bit under the bus and declare > freebsd to be a 64-bit-only OS.

Who know if that will be the case in 4 or 5 years when 14 is branched (so ~2025). Current trends suggest that 32-bits might not be relevant then, but we certainly can't say that for sure today.
