Comment (by simonpj):

 Yes, GHC's API and plugin interface exists to make it possible (and as
 easy as possible) to build new tools on top of GHC.  It has evolved over
 time, but needs love, and thoughtful development.  So thank you for
 offering some concrete suggestions.

 Clearly we want any new extensions to serve as wide a group of clients as
 possible.  Sharing the proposals as a GHC proposal has proved to be a very
 effective way to improve ideas by discussing them with others.

 It would really help to have a couple of example use-cases to motivate
 each of the proposed plugin extensions.

 Thanks!
