I don't doubt that. But the price of attestation, if it's not properly isolated from the hosting OS (like Microsoft's completely unrealistic attempts of bringing the whole OS into the trusted computing base, kernel and applications and all), would be a homogeneity of computing I don't think is necessarily worth the benefits.
The good news is that such proper isolation is not only possible but even desirable (it keeps the trusted computing base small), and if done well could actually replace annoying half-measures such as "root detection": Who cares if my phone is rooted, as long as my bank's secure transaction confirmation application is running in a trusted, isolated enclave, for example?
