Not "instead", but "as well as". You can't infer lanes OR width OR
surface from highway=*. In the same way, I expect that I would not be
able to choose an informed cycle route based on someone tagging
hazard:cycle=2. I'd rather know what the hazard is - high traffic,
potholes, narrow lanes, hills, etc.

If you insist, go ahead and use hazard:cycle=2 - it doesn't bother me,
and may have some use as an interim solution - but I think we should
ultimately aim for a better solution, that is, more specific
information "at least as well as" the vague information.
