Has there been any further discussion on the qualifications for Windows 11 with regard to Processor requirements or alternatives to TPM ? Does Intel have any further information that would clarify why certain processors were chosen or not ?
Microsoft has never explicitly said why TPM 2.0 and processor generation were hard requirements, but this is why:
HVCI (and the features that depend on it) is very slow and cripples some CPUs by up to 30%, but with the MBEC feature released on newer Intel and AMD CPUs, it's much faster. Microsoft wants to enable HVCI by default (and probably just want to block the CPUs that would get too slow instead of dealing with the complaints).
TPM 2.0 (instead of TPM 1.2) is officially required because of some extra, lesser used features. Pure speculation, but they might also develop new security features that require TPM 2.0.
