I frankly don't understand what you are saying here.  Several people
opined that we should take a broader view on the fixes and how to
handle them, but you insist that Flymake should have its own solution?

IOW, the "fixes" diagnostic shown by Flymake is not just diagnostic,
it's a suggestion to make some change in the source code.  So
supporting that cannot be separated from the more general concept of
making changes proposed by some external tool.  Or what am I missing?

Or maybe this is a simple misunderstanding: what do you mean by
"acting on diagnostic at point", and how could such an act be
indifferent to what and how is fixed?
