Honestly, I find your position of "surface and width is what you map,
everything else is subjective" a little extreme. Consider the tags
"highway=service", "highway=unclassified" and "highway=track". They cover a
wide range of surfaces and widths. What unites them is that four wheeled
vehicles can do use them. I don't see why the standards for bicycle access
should be higher. If bicycles can and do use certain paths, then let's map
it so. Obviously, recording surface and width *in addition* would be nice,
but it's not essential.

Do you really think you can define every existing tag to this high standard
of objectivity? I don't. So, I'm quite comfortable mapping out bike paths
and pedestrian footpaths, knowing that I will get some of those in the grey
area wrong, and that someone down the line can quibble over it and fix it.
I'd rather get 90% right with a small amount of effort, than 100% right with
a large amount of effort. Or worse, map 50% that are "objective", and leave
the other 50% unmapped because I didn't have all the information required to
be certain.

I understand that you want beautiful, objective, highly detailed data
everywhere. We all do. My thinking is "low quality data everywhere first,
then medium everywhere, then high everywhere". Yours might be "high quality
data in small areas first, then in bigger areas".
