The trouble with that sort of thing, as compared to (ignore the actual
tag names, they are just to give an idea):

bicycle=yes
bicycle:surface=poor

(i.e. splitting out access from quality) is that the former scheme
doesn't have fallback - i.e. renderers have to know about all possible
values anyone could invent, whereas the latter scheme has a "simple"
version for most maps and then cycling-specific maps can bother with the
extra complexity.
