ATM all places where we use
maybe_upcast_putmask
haveother
as a scalar. By making that into a requirement for the function, we can rule out the possibility of passing non-scalar other intomaybe_promote
(xref #29331).Note: there are some simplifications within maybe_upcast_putmask that this makes possible that I did not implement in this PR.
