Agreed.

Rui, the naming '.bind_to_tz()' seams to be appropriated here, even
considering the validation perspective you mentioned. Binding to a
thermal zone should be the best opportunity to check if the zone makes sense
for that governor. Don't you agree?

I think the .bind_to_tz() should be enough for both cases.
