It shouldn't be? I got a new AM4 board a year or two ago and almost every board on the market at the time had TPM2.0 slots. The issue was that they aren't advertised and barely mentioned but they were there. From taking a quick search, I selected the first AM5 motherboard I saw from ASRock, MSI, Gigabyte, and ASUS. All had TPM headers buried in the specs or only listed in the manual. Caveat that with ASUS it seems the ROG boards don't have TPM headers but the equivalent ASUS non-ROG boards consistently do. Point being that they are still quite common and if that's a feature you care about, it's easy to accommodate in any build without even having to look for a different brand. The only issue is that they aren't well advertised or advertised at all.
