Well, I stick around and am usually aware of GHC release early. In the
usual case Haddock will be fixed up before the actual GHC release. I
don't think API changes were ever drastic enough to provide major
problems especially seeing as I'll be able to refer to the GHC-tracked
branch to see what patches were applied there.
However let's consider I can't make it for the release because I'm not
available around that time or otherwise. This should still not hold up
GHC release. I would expect the GHC team to release Haddock + their
fixes, it would simply be like an existing release with some patches on
top to have it work with new GHC. I can then come around and once I
apply any API patches, I make an actual Haddock release. People can then
simply cabal install haddock and use what they get here rather than what
came with GHC.
Does this make sense?
