They don't because if they put numbers and also described the usual clinical course of these cases it would show the issue to be a nothing burger.

The numbers I saw were about 1.0 per 100k were hospitalized for 2-3 days. No deaths and half those recovered completely after a month.

I haven't seen anyone say this but that's probably the same risk of myocarditis you get from the flu. And 100 times lower than the risk from covid.
