Definitely.  But still, even a generic *something* for path (to be then
highlighted with the blue border (from cycleway=*?) would be nicer than
showing nothing at all.

Not sure if you’re writing about the many access-variant keys or the
several access values that are similar in meaning to “yes”.  If the
former, I’d think you only need to care about bicycle for the cycle map,
would you not?  It’s certainly much worse if you want to highlight
designations for several modes of transportation...even 2 gets unwieldy.

As for the values, for a cycle-map I’d be inclined to not even highlight
anything which has only bicycle=yes, because it would quickly overwhelm
everything else – perhaps it’s different where you are, but around here
all roads except motorways (and possibly a few others, specially signed)
allow bicycles and would thus be bicycle=yes (or would be, if I would be
bothered to fully tag every road like that).

Beyond that there should be only bicycle=designated.  There is also
bicycle=official, but perhaps that can be preprocessed into access=no +
bicycle=designated before rendering begins?  The meanings are the same...
