yes, rejected ;-)

a good example where it didn't work either: there are 1.2M of
highway=bus_stop but only 200K public_transport platform and stop_position.

there are also fixed lanterns, and there is even another use for it in
architecture, probably you'll find it in this context as well
(building:part etc.)
fixed lantern: http://en.wikipedia.org/wiki/File:Lanterna_cafoscari.jpg
architecture: http://en.wikipedia.org/wiki/File:Laternebap.jpg


One could of course also think of not using man_made at all, and

You could use man_made=pole / post / mast / tower /... for the
support/structure (if mapped on a node).

What would be other values for this new key?
Checked it, actually "light" is taken:
http://taginfo.openstreetmap.org/keys/light#values
but "light_type" seems available (zero usage as of taginfo). There is 337
of "security:light_type" which supports the idea that "light_type" is about
the type of lightning device
http://taginfo.openstreetmap.org/keys/security%3Alight_type and also the
"lamp_type"s support this reading:
http://taginfo.openstreetmap.org/keys/lamp_type (they do not refer to the
fixture).

cheers,
Martin
