That is all true.  ABI compatibility would be nice. But I don't see how to combine with GHC's other goals.  Notably, we frequently add new information to interface files, and it would be a major constraint not to be able to do so.

For the present at any rate, ABI incompatibility between major releases seems like the lesser evil.
