Hi Spencer,

Thanks for taking a look.

I don't think adding a command for fixing the diagnostic at point should
preclude any other developments or explorations.  It's a useful thing to
have, and many Flymake backends have the needed data readily available.

Flymake shows diagnostics, and "fixing" is what we do to diagnostics.
What would be the benefit of a Flymake-independent UI for fixing the
diagnostics that Flymake already shows?
