Also, is this really a warning or just a debug message? (everything
seems to work fine on Juno even if this is printed :-)).

I would consider it a warn; this _should_ not happen. If your platform
supports fast_switch, then you really rather want to use it.

Mmm, right. So, something seems not correct here, as I get this warning
when I select schedutil on Juno (that doesn't support fast_switch).

There is a mistake here.  The message should not be printed if
policy->fast_switch_possible is not set.

Will fix.
