Fat interface files?

[Edward Z. Yang]

Hi Ben, sorry about the late response.  It looks like you've found
https://gitlab.haskell.org/ghc/ghc/-/issues/10871 which I think
pretty comprehensively discusses the issue as it is.  Given the
elapsed time it would probably make sense to reimplement from scratch;
I don't recall this being too difficult to do.  HAs anything else
come up in the meantime?
