Xmobar is a status bar that can be configured in haskell by using it as
a library, similarly to xmonad. Yesterday I fixed my own channel so I
could do a guix pull and noticed that after it I no longer could
recompile my xmobar configuration. Apparently the library part of the
xmobar package was removed in commit 6188fe26334. Should this be fixed
by reverting that commit or by adding a new package, ghc-xmobar, that
provides the library?

I think the library should be included in the same package, just like
the xmonad package also includes the xmonad library and not just the xmonad binary.
