The problem this makes is that Google enforces its monopoly over the whole Android ecosystem and blocks anyone else from making a ROM with working apps. The European union is fighting hard against cases like this and there is a great precedent for it to be illegal

There is a hardware attestation API that can be used by any Android based custom ROMs that follows best security practices and that is probably more secure to use than Google's proprietary APIs
