I suppose that's my fault for not marketing more, the code 
generation is tested in LDC's CI pipelines so that is unlikely to 
break, and the library is built on slow moving APIs that are also 
unlikely to break. Just because it doesn't get a lot of commits 
doesn't mean its going to stop working.

As for specification, I think that would be a wasted effort and 
too constraining. On the compiler side, it is mostly using the 
existing LDC infrastructure with (more than) a few hacks to get 
everything to stick together, and it is heavily dependant on LDC 
and LLVM internals to be part of the D spec. On the runtime side 
of it, I fear specification would either be too constraining or 
end up out of sync with the implementation.
