...and while we're talking about "questionable utility"...

COMPAT_AOUT_M68K, COMPAT_M68K4K, and COMPAT_VAX1K are merely exec glue (well, mostly; COMPAT_AOUT_M68K has some ancient stat()-related emulation) for what are, at this point, ridiculously old a.out binaries that you also need to have the entire a.out runtime for.

I would say at this point that nobody has any business running these ancient a.out binaries.  All of these platforms switched to ELF **long** ago.  Even though these layers are extremely thin, a reasonable argument could be made that these should go, too.
