Not really. All those targets will need runtime support from the 
foundation. As is, runtime support aside from X86, AMD64 is 
somewhat lacklustre even on GDC and LDC, and it's not easy to 
produce runtimes.

In my opinion it's best to have a bleeding-edge implementation 
that the foundation can work out language issues and experiment 
on and then other compilers that can focus on multi-targeting and 
LLVM/GCC interfacing.
