Can you clarify what you mean by active? Is it visible? Or in some container?

Done.

I'm a bit hesitant to require other parts of the UI directly telling
MaximizeModeWindowManager about these things, can we find all inactive multi
profile windows from MaximizeModeWindowManager::MaximizeAllWindows or detect the
state change using observations?

As discussed offline: This decision did not came easy, but given the constraints
this is the best which can be done here. I experimented a day with alternatives
and this is optimal. - So I leave this as is.
