That's not a bad thought, but it would require connecting the
street-side parking area to the highway (e.g., by extending the area to
the middle of the carriage way), which goes against the principle of
mapping what is there. I don't think renderers tend to have this
information available in any case.

Another notion I had was that renderers could just use capacity=* as a
measure of how visible a parking amenity should be, but that would
require knowing the capacity, which is not always plausible (and it
could lure mappers into tagging a capacity value they deem suitable for
rendering reasons). Of course, using capacity=* as well as parking=* can
be useful to highlight huge parking facilities at an earlier zoom-level
(I think Carto uses only the area size at the moment to do this).

All in all simply adding this sub-tag value seems the clearer option.
