I think that ship has sailed, since the meaning has been in use for almost 50 years now.
As someone who can't stand the use of "they" as a singular pronoun, I also understand fights against the evolution of language are battles that I won't win.

Please please don't say that. It is not being used to mean that. It is being used in a figurative way to mean "very". This is an ironic but relatively minor shift. It's in no danger of becoming its own opposite.
Vanilla = plain is a metaphor.
Singular they is a syntax issue.
These are processed totally differently in our minds/brains. Both we come to accept with enough usage and good attitude, but they have very different significance in language.
Most people who don't start knowing singular they find it a true syntax error, the sort like a P600 response in an EEG test. It's deeply irksome. But then with familiarity, it goes away.
Metaphors don't have such a deep language processing issue, they just have semantic meaning that we accept or not and our objections live at a far more intellectual level.
