Alas, that's true: Today I had to unbreak the "time" package exactly because 
the .cabal format has been changed.

Fair enough, but giving a painful birth for months after months is really 
annoying. Our very big mistake has been to use Cabal in its current immature 
state in the GHC (+ libs) build system. Being progressive and open to new 
technologies is a good thing, but *not* in the area of versioning systems, 
build infrastructure and the like, at least this should be avoided when the 
SW in question is built by a large amount of people. Experiments should be 
done in isolation...
