FYI, here's the schema I personally use in Sweden, where heavy use is
made of ramped staircases, though not thankfully on major cycle routes.
My objective is to allow routers to intelligently route for both
sport/club/large group riding and happy meandering or commute:
bicycle=yes only on very shallow low incline steps where it is is safe
and practical to cycle an ordinary bike - not common but does happen.
Sometimes on shallow slopes a gravelled or informal path to one side
also exists.
where there is a ramp:
ramp=yes
bicycle=dismount (here I am tagging on practicality rather than
legalities, Sweden is much more relaxed than UK)
ramp:stroller=yes where it is a double ramp, (a forgotten transport
demographic)
on short or low-incline flights of steps where an alternate route would
be much longer:
bicycle=carry (informal/experimental)
I also strongly encourage step_count=x as that gives a bicycle router
more quantitative input on whether to route or avoid.
And lastly from unnerving Spanish experience, some sort of hazard
tagging at the top of steps where a formal cycle route plunges down a
steep flight of steps around a corner!

bicycle=dismount should be used for 'signs saying "Cyclists dismount"'.
Any sensible router should know that most bicycles ought to dismount
for most steps in the same way they might suggest getting off and
walking on a short footway. Specifying bicycle=yes on steps may
override the built-in default (I think it does for CycleStreets).
I would suggest not having a bicycle tag at all on steps in preference
to bicycle=yes on steps. Ramp:bicycle=yes/no is a useful tag though.

Only if it is illegal to try to cycle up and down the
steps. Otherwise
it is the duty of the renderer (router) to infer that
this will be
necessary because of the steps.
The sign visible on Mapillary says (white on blue) "Steps
ahead cyclists dismount". That seems pretty clear to me.
White on Blue ‘cyclists dismount’ signs are only advisory. It
may be foolish to cycle down (or up) the steps but it’s not
illegal.
