If we had those things, indeed they would!

However, beyond A (GHC 7.10 was tested more extensively against
hackage/stackage than any previous release of Haskell by far!), the others
require various degrees of engineering effort, including some way to deal
with refactoring code that already has CPP in it, more extensive build-bot
services, etc. and those sort of non-trivial artifacts just haven't been
forthcoming. =/

I would be very happy if those things showed up, however.
