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. 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.
Of course, I'm not volunteering to do the work, but still ...
Thoughts?
