Lots of articles on this.. i suspect similar issues of security and performance for the reason mac deprecated that hardware too on current os.

Macos 12 runs on Ivy Bridge 2013 mac pro's and haswell mac minis, so on their side it wouldn't appear to be a technical limitation of the older CPU's. Apple does their trusted stuff on the T2 rather than the Windows generic TPM 2.0 requirement, but interestingly the 2013 mac pro lacks a T2 as well. I think TPM 2.0 was a 6th gen skylake onwards thing?

Don't see any that explain what specifically changed that made it not work.
