Perhaps @nullptr.cpp could add something there? The file is `clang/docs/ReleaseNotes.rst`.

I am not certain we want it directly under that flag, but it may make sense as a subgroup of `-Woption-ignored`. e.g., I can imagine a use case where someone wants to silence that they're using a deprecated flag (so their -Wx builds continue to compile) but still wants to be warned when they use a option that's ignored for other reasons.

You're right, the other flags `-Woption-ignored` warns about seem to have an effect on compilation such that one might want to be warned if they're ignored. Which isn't the case here, I guess.

Also it's probably Ok if people just see that the warning no longer exists and then remove it, or remove it based on the compiler version.
