That's partially true- it's true we have no official tags, but it's
also true that the tags which are approved are the ones which get
rendered, and the ones who people write software against.

I'm of two minds on this, so please tell me why this is a bad thing in
your mind?

I'll admit I'm a bit frustrated because I  have a very pragmatic
problem to solve and have spent several weeks trying to make practical
tools to solve it, and I feel David wants something else entirely and
is suffering from a bit of NIH syndrome, and Josh (who I think is
actually local to me) doesn't see what I'm doing because I haven't
announced it yet.

But maybe you'll have some feedback...

Go to http://mappingdc.emacsen.net/pl2/

and what you /should/ (hopefully) see is a map of DC, and you can
select DC SIdewalks as a background.

That's real DC sidewalk polygon data. But it's too complex. I'd like
to attach those as information about the streets.

Also if you  look at the stylesheets, you'll see Pedestrian Wireframe-
that's a style I've created that highlights sidewalk data, missing
sidewalk data, and highway=footway.

In other words, I'm trying to make it as simple as possible to get
this data in OSM, without an import.
