Thanks, as my mapping matches that documentation and the discussion on the
wiki I'll leave it as it is, ignore the OSMI errors and contact Geofabrik
to suggest the tool picks up this usage.

I've come across a few different cases. The obvious cases are where there
is a driveway running parallel to the road with a signpost. In some the
terrace is marked by a sign attached on the side of the buildings, which
front directly onto the road. Sometimes there aren't any sign at all, and I
only know because there is a business with an advertised address or - as
with one at the weekend - I asked somebody who was going into their home!

For the latter two, splitting the way as you suggest is the only solution
I've come across. Adding phantom roads, as in Philip's example, isn't
really mapping what's on the ground.

Tom
