Actually, it would be even nicer to have indications of features on the
higher zoom levels as well.
Like in many professional tourist maps, where on a low-detail zoom level
you will basically see *one* pub symbol and *one* camping symbol next to
the city name, telling you that there is at least one of these POIs
there, and if you zoom in (or look at the detail map on the reverse side
or whatever), you get to see where they are exactly.
Same with road names; a debug map should have a visual distinction
between "there is something here but not enough space to display it" and
"there is nothing here".
That's one thing I like about tiles at home versus Mapnik - on a planet or
continent scale, the t at h map has an indication of "there is something
there", something that the Mapnik map doesn't offer.
But then again, the existence of such a debug map will not keep people
from complaining that their data does not appear on "the map" ;-)
