Yeah, if/when it goes in for AArch32 it ought to go in the docs. The option means 'only use the general registers', so both fp and neon would be disabled.
I haven't thought through what this means on the AArch32 side, or whether it amounts to -mfloat-abi soft. Your question hints that NEON is still available with softfloat - which, given that there are integer NEON operations, would make sense.
