I have mapped many traffic signals (and, for that matter, stop and yield
signs) based on shadows visible on the satellite photos. If you look
carefully enough (Bing and Mapbox Satellite at least), they are there.
(Local knowledge helps too in some cases.)

I agree that the current presets available in JOSM are a bit of a botch,
particularly "uncontrolled" for crossings technically controlled by a
sign. "Marked" may be better but we still have the issue of changing a
lot of previously tagged crossings. I think "island" is already covered
by traffic_calming=island, no?
