Given almost all packages are maintained by the DHG, a full round of
sourceful uploads should be doable. But without the Provides on the old
name, all Haskell programs would FTBFS, which would be not so nice... so
yes, the Provides should be added.

Marco, you recently worked on the -dev name consolidation, and thus know
about clean package renames. What modifications should be done to rename
the packages now? These should probably be implemented in

Speaking of sourceful uploads: Should we start building -dyn packages?
At least people building local binaries would probably welcome that (as
already expressed on this list).

If yes, should we use them in Haskell programs (xmonad, hlint, etc.)?
Pro: Smaller packages/binaries and shared code. Con: Binaries will have
to be binNMUed upon new uploads as well.
