Since it is dependent on municipal bylaws then I think it should be
explicitly tagged.

The reason why we were asked to add them is for pedestrian security
assessment and urban planning. When all sidewalks and crossing are
mapped, we can measure crossing distances and estimate the probability
of accidents, which can save lives when the cities add curb extensions
(avancées de trottoirs). We use openstreetmap data to convince
government officials that it is statistically better to take them into
account when planning new neighbourhoods or enhance existing ones.
Also, it allows us to get better precision and calculate penalties
when routiong at traffic signals which must be crossed twice by
pedestrian at some intersections. OpenStreetMap objective is to map
what is there with the best precision available. When aerial
photography was not precise enough for sidewalks, it was not feasible
to add them, but now we get precise aerial photos that permit better
representativity of the physical world. I can tell you that the amount
of precision and completeness in openstreetmap data will increase
rapidly in the coming years. And the COVID-19 pandemy will increase
the need for precise and complete mapping of urban environments, so we
must deal with it accordingly.
Mapping sidewalks as separate ways is now in the official wiki and has
been accepted by the community by vote, so we must now find the best
way to accomodate everyone. For now, I am just trying to know if we
must add bicycle=no to them.
About the routing directions, we must add the street names to
sidewalks (as we do in my team), otherwise like Martin said, routing
engines will tell people to turn left, turn right instead of turn left
on A street, then turn right on B street, etc.

What cities allow cycling on sidewalks anyway, seriously ? This
sounds so inadequate. That it is tolerated is one thing, but
outright legal or encouraged ? Makes no sense to me.
In the US that's pretty common. For example here in Madison
(Wisconsin), sidewalk riding is generally allowed by ordinance,
except where buildings directly abut the sidewalk (I manually tag
those as bicycle=no).
