Has it been?

I don't see any slippery slope here, just a handful of functions that 
any reasonable freestanding implementation is going to want (memcpy, 
etc) and some way of getting an error out (raise/abort).

If it starts wanting libc functions that aren't reasonable, then of 
course we should complain (possibly with patches, for those willing to 
deal with the copyright assignment process).
