Spurious recompilations when using a compiler plugin

It appears that use of GHC plugins causes client code to get needlessly
recompiled. (See Trac issues 12567
<https://ghc.haskell.org/trac/ghc/ticket/12567> and 7414
<https://ghc.haskell.org/trac/ghc/ticket/7414>.) It’s becoming more of a
problem for usability of the plugin
<http://conal.net/papers/compiling-to-categories> I’ve been developing, and
I’m wondering what can be done. Some questions:
- Is there any work in progress on fixing this situation?
- Are there serious obstacles to fixing it?
- Do plugin writers or users have any workarounds?
Other insights appreciated.
