Yes, requiring RSA-PSS causes interoperability issues with smartcards that 
don't implement this 16 year old algorithm. But being able to say "if you're 
using TLS 1.3 that means you are not using legacy crypto" has non 
insignificant value too.

This document erodes that.

So I'm against adoption of this draft by the WG.

If it is adopted, I will review and provide feedback on it.
