I think that's a bit naieve.

There are still lots and lots of "noname" roads in London, particularly in
the poorer parts of outer London. Road names are really very easy to survey
and add in.

After all of TimSC's work there are large parts of London without landuse
areas.

Whilst Harry's mapping parties have done wonders for POIs in Central London,
the rest of the city has very patchy coverage.

Even cycle routes are incomplete and cycle parking coverage is very limited.

Mapping buildings based on surveys for accuracy is laborious by comparison,
and even after a year or more of experimentation by a few brave souls a tiny
percentage of London has seen any activity.

I'm inclined to support a mass import of automatically traced buildings with
a noname layer equivalent, or a modification to noname, to aid verification
and improvement by people such as myself who are interested in doing
buildings properly.

Best,
Tom
