In the US, a few (mostly east-coast) states have peaked. West, central, and mountain, and south, not so much.
Given limited services and long distances in rural states, masking would be highly advisible.
(Numerous highly-advisable actions have, of course, been soundly rejected.)
Both the practice and empirical data on its efficacy would be useful in parts of the world Omicron has not yet hit.
I do agree the advice would have been far more useful 4--6 weeks ago. Call your local Timelord.
