The size issue with single-layer media has been a known issue since the
CentOS-6 days and the release notes very much do mention it, or at least
they did at one point.

It's not realistic to expect server-class machines not to be able to
boot from dual-layer or USB media in 2021.

Certitude is not the test of certainty.  We have been
cocksure of many things that were not so.
