Given the number of different people that have sent in patches for building with VS2019, it doesn't seem to me that we ought to let that wait for v13.
I am not so sure if there are actually that many people or it's just me making too much noise about this single issue, if that is the case I want to apologize.
We could treat it as something that we only intend to go into v12, or we could think that we ought to back-patch it, but either way it should be on the open-items page somewhere.
There is already one item about this in the commitfest [1].
Of course, I'm not volunteering to do the work, but still ...
After all the noise I will help to review the patch.
