I'm fine with haskell@ and haskell-bugs@, it's haskell@ and haskell-devel@ that I feel is odd (as compared to fedora@ and fedora-devel@).
I guess as long as haskell-devel is mainly for bugzilla traffic then haskell-bugs makes sense. Of course the mailing-list is also the address of the haskell-sig pseudouser and in principle could also receive other mail in the future like scm commits, which could be one argument for keeping the name haskell-devel.
Anyway the pseudouser address needs to be updated anyway to the fp.o list. So any renaming could be done at the same time. Let me try to check later with fedora infrastructure how easy it is to rename a list anyway.
