How is it more feasible to ask her to write such customizations
inside a string than asking her to write the same customizations
in a symbolic expression?

I'm sorry, but the patch you pushed is crucially flawed, it simply
banishes the indicator in every file without diagnostics in the
"note" category.  This is plain to see in many Elisp files, but is
not only for Elisp, it affects Eglot and likely other uses that
rely on Flymake.  Since I don't know how to fix your "format-spec"
mini-language in the very short term, I hope you understand I
had to revert your patch.

In other words, the problem at hand doesn't get any simpler
just by choosing less powerful language. Either we make
the language more powerful, or we choose to solve a narrower
problem.

I don't understand your "don't care" comment.  You don't care
for enhancing format-spec to allow for conditional formattings.
Or you don't care for Flymake or what?

João
