Well, this touches on another issue, and that is that jhc is a native
cross-compiler. It never behaves differently if compiled by another
haskell compiler or is compiled on an alternate platform. There is never
a need to 'bootstrap' it, once you have jhc running anywhere then it is
as good as it would be if it is running everywhere. So to me,
self-hosting has never been a big issue as it doesn't provide any direct
"material" benefit. My time is better spent implementing more extensions
or improving the back end.
Of course, if jhc were to have a back-end that ghc didn't support that
was a useful platform for jhc to run on, then it would be a different
story. There would be a direct material benefit to having jhc being
self-hosting so it would become a priority.
