That's the current situation. So, the worst case scenario, with this tag,
is...what we have now. Every other case is an improvement.

Not sure which tag you're referring to. If the tag is just a bit of
decoration, maybe you don't need a fallback. But in lots of other cases, it
would be good to be able to fall back to at least a landuse=industrial, or
building=yes or something.

Nah. Only the smart mappers would even think of using it.

Nah. It doesn't matter enough. I would see it mostly as a personal thing for
the mapper, to know that at least *something* will render.

I would think a better idea is to have atleast one renderer and the main OSM

There are hundreds of thousands of distinct key=value pairs. And even if
that was one renderer could do it...how does that help? Say I want Mapnik to
look nice, but you propose that I use Osmarender instead because it supports
every single tag.... This isn't a solution at all.
