There is a distinct difference here. If I create a way around a farm or
whatever its logical to label it landuse. However on the whole what I am
defining in these POI's is part of a location, an address. These are nodes
giving the name of a place or feature, they are not landuse or indeed in
many instances natural either.

If I get around to creating the enclosed wood then yes I'd tag it as
landuse. There might still be a benefit of maintaining the node with the
name but I agree that level of duplication shouldn't really be necessary.

That would seem the simplest way of picking up map annotations. It's a lot
easier of course to do it under one subset that under a whole set of
different ones.

Not sure I follow you here. I'm not aware I've ever used highway=minor for
instance.
