Clarification: Browsers or other user-agents are not required to trust QWACs for use in TLS. We fought very hard for this.
However, there are obligations to display 2-QWACs if sites choose to use them. Their keys are not used to authenticate web domains or encrypt web traffic.
Disclosure: I was Mozilla's lead for this effort and also helped design 2-QWACs (for my sins).
