The vaccine mandate discussion really doesn't apply to the new CDC guidance, yes we need more vaccinated.
The new mask requirements for vaccinated/all is because the CDC determined that vaccinated people can spread the virus as much as the unvaccinated. They are/were very clear on that. Even moreso the metric for where people need to be masked is based on transmissibility not vaccinated rates. so whether or their is a vaccine mandate or something like it is moot in regard to the current guidance.
This is strictly about number of cases now as the guidelines and metrics show. The metric is not low hospitalizations, it is only about cases.
Note they also newly recommended on Tuesday, if a vaccinated person is exposed to a positive they should be tested even if asymptomatic and quarantine for ten days if positive. That is only going to increase cases even more. Masks at Disney are not going away any time soon at all (perhaps a few months early fall, when cases drop, then back on in late fall/winter). The mask recommendations are not about being unvaccinated, perhaps on a meta level, but not in reality where it is all about cases.
