Once again I had to revert your "corrections" because they falsified correct or meaningful tags.

Please stop blindly working through lists without dealing with the local situation (e.g. with street photos) or without trying to understand what mappers might have had in mind when tagging.

In this case, I recommend wiki pages https://wiki.openstreetmap.org/wiki/Tag:sidewalk%3Dseparate and https://wiki.openstreetmap.org/wiki/Tag:bicycle%3Doptional_sidepath, which you could have found/be aware yourself.
