I’m all for it.   We could add the new spellings as synonyms of the old ones; and deprecate old ones.  Then drop the old ones after a release cycle or three

I have renamed it to -Wmissing-pat-syn-signatures.

Hmmm, things are still wildly inconsistent:

   * "pat" is spelled "pattern" in other flags.

   * We still have both "sigs" and "signatures" as parts of the names.

   * Why is "synonyms" too long, but OTOH we have monsters like "-Wnoncanonical-monadfail-instances"?

   * We have both "binds" and "bindings" as parts of the names.

My proposal would be: The -Wfoo option syntax is new, anyway, so let's fix all those inconsistencies in one big sweep before 8.0.1 is out, it only gets harder later. At the moment you need #ifdef magic in the code and "If impl(foo)" in .cabal, anyway, but doing these changes later will only keep this sorry state for longer than necessary. I don't really care if we use abbreviations like "sigs" or not, but whatever we use, we should use it consistently (personally I would prefer the whole words, not the abbreviations).
