From the explainer:

> However, a holdback also has significant drawbacks. In our use cases and capabilities survey, we have identified a number of critical use cases for deterministic platform integrity attestation. These use cases currently rely on client fingerprinting. A deterministic but limited-entropy attestation would obviate the need for invasive fingerprinting here, and has the potential to usher in more privacy-positive practices in the long-term.

I think any holdback will eventually go away because of the "critical use cases for deterministic platform integrity attestation"
