(You meant to type aeroway=tower here)

I've noticed this too. The use of service=* seems wrong here; perhaps
this was introduced before tower:type became a thing?

Based on existing tagging practices I would say that
tower:type=aircraft_control is the right tag to use in addition to
man_made=tower. Adding aeroway=tower to that mix seems harmless enough
if you look at the three tags like this:

  Fulfils the active role of aircraft control tower (function)

  It is a tower (physical characteristic)

  This tower is an aircraft control tower (physical type)

The latter two can always be applied as long as the tower is standing,
but I would guess that aeroway=tower can only be applied to those in
active use for that particular function.
