Nah, many of these are implementable without changing the compiler:

Needs exception support, of course

Easy (no forkIO)

nhc98 must have something like this already.

All implementable using the FFI only

Ok, MArray and IArray need MPTC, but you don't actually need unboxed
arrays (Hugs provides these).
