This is probably easier for newcomers than for people who just got
used to the current way of doing things.

I don't think complexity is a big issue here because it makes the
tagging more consistent.  Instead of thinking nodes/ways/relations one
needs to think points/(poly)lines/objects.  Everything you want to map
is an object, most of which need to get a geographic reference as one
of its attributes.

Of course this needs editor support, but I don't think it needs to be
very slick.
