Oh, definitely.  That's why I think we can make one good enough.

Pretty much. Not quite that, necessarily, but more if there is only going
to be room for one name, that's the one everybody would expect. It's not
more important, so much, as better known.

That's pretty much it. I usually refer to my work place as being in the
suburb next door to the one it really is in - many more people know where
that is (even if just "oh, somewhere on the north edge of the city") than
have heard of my real location. Only if I have to give an address do I
actually list the real suburb.

For each small grouping of suburbs/localities, if you asked a bunch of
people from within say 100km which of their names should be shown if there
was only room for one, you'd generally get a pretty good consensus. How we
get our renderers to know that is the problem.  I'm not sure relations are
the best solution - I'm not saying that A should always replace B & C, just
if I have to pick between them I'd pick A.  If I can fit both A and C, then
that's fine.

I haven't come up with a good solution. There's no objective, visible on
the ground, easily verifiable data I can think of that we can map to handle
it.  But the effect is real, and if we can utilise it, it will make our
maps feel better.
