I don't believe that's the case, but I might be missing something. UMIP makes a system more secure, but it isn't a hard requirement for any feature-wise assurance? For example, TPM+UEFI+Secure Boot is required if Microsoft wants everyone to have full disk encryption by default, which makes sense. UMIP, not so much.
