I disagree. I think people would be *more* motivated to add tags if
they see that there is something there already, but they want their
street to show up properly with names and colors for primary roads etc.
Also I think it is harder to start your mapping in an area where there
is nothing, because you'll think it is futile anyway. But if you see a
start somewhere you might be induced to help adding to it.

Hm. Is worth considering, but I think this would be confusing for
outsiders who look at the map. (Not that Osmarender maps aren't very
colorful already with all the different abutters etc.)

So I think a faint dotted gray line would make it visually clear to
everybody that there is something there, but its not finished yet.

Maybe we should try this out. Can anybody point me to an area where
there are untagged segments without ways (and also tagged ways for
contrast)? I'll render them with different rules and we see what it looks
