I think the idea is to give it more prominence: if you go to
http://hackage.haskell.org/package/parsec, the version that hits you
immediately is 3.1.0; it isn't as immediately obvious that there is a
new parsec-2.x version out.
That said, if parsec2 is only a bug-fix branch of parsec-2.x, is there
any particular reason work couldn't be done to improve the performance
of parsec-3 when using the compatibility layer (and even improving the
performance of parsec-3 overall) rather than a specific branch/fork?
Unless the API changes from either parsec-2.x or the compatibility
modules in parsec-3, I'm not sure how much use this would be; as it
stands, in Gentoo we already tweak a lot of package cabal files to
remove the upper bounds on parsec some of them impose, and we're
likely to do the same to make packages that use parsec2 just use
"normal" parsec instead.
