TPM 2.0 was finalized in Nov 2019 after the above system was built. Hardware isn't progressing that quickly anymore which makes a hardware requirement like TPM 2.0 very arbitrary honestly.
Microsoft could have easily made Windows 11 work without TPM 2.0 as the workarounds attest to. It could have been "if you don't have this, you don't get some security features but otherwise it's fine".
My conspiracy sense is tingling at the hard requirement for TPM 2.0 that really doesn't need to be there. A bit like when MS bought Skype and moved it from peer to peer voice to a central server based system with no monetary gain from doing that, someone obviously decided that needed to be done. We don't need to be asking people to throw away perfectly performant hardware to upgrade. There's actually nothing in Windows 11 enabled by the requirement since Windows 10 also supported TPM 2.0 already, it just didn't require it. I've also never been subject to the attacks TPM 2.0 protects against. There may be cases where TPM 2.0 is wanted, i can imagine it's useful for servers, but i really don't need it.
