It would provided users would do full system update from aur (or our 
archhaskell or whatever the name will be). The system update would 
recompile all dependencies when updating them.

In general, the problem with haskell libraries is that any new version 
of a library is not binary backward compatible with the previous 
versions. AFAIK, there is no clear way to tell what is part of a binary 
interface of a library and what is not; so there is no easy way to tell 
whether a new version would be binary compatible or not.
