And it regularly causes annoying dependency issues, including causing cabal
to regularly do diamond dependencies.

Somehow the Haskell community is hellbent on repeating the mistakes every
other community learned about the hard way years ago, especially in the area
of dependencies (first refusing to acknowledge the need for upper dependency
limits, more recently trying to avoid adding an epoch — and I'm not counting
how packages included with the compiler but not recognized as such by Cabal
lead directly to Cabal introducing diamond dependency failures).  Is this
*really* necessary, or should those of us who've seen it before just sit
back and watch you all ram your heads against the same brick walls?

(Why no, it doesn't look like a brick wall now; that's the point.  It
*will*.  Learn *before* it happens.)
