All excellent suggestions thanks.

We've never run into this situation before, because there wasn't a FREAKING
GLOBAL PANDEMIC for nine months before the EOL date. We had started
upgrading our 150+ machines before March 2020, but then, well... you know.

It turns out we do something similar to number 2, so we'll probably be OK.

Maybe the CentOS folks could just drag their feet for a few weeks to give
other folks a little break.
