According to OSM wiki history, `bicycle=dismount` is a pretty recent

much earlier. Hence it is you who wants to redefine a well established tag.

According to the first version of access=* in 2006:

Yes, my guess is that early mappers felt no need for bicycle=dismount
because it was simply presumed that foot=yes + bicycle=no meant the same
thing -- the assumption of a very bicycle-friendly culture!

The obvious problem with bicycle=closed is that it's rarely used so
routing software will probably not be looking for it, and so will
happily send bicycles along bicycle=closed ways. In fact, I wanted to
test some routers but I can't find a single bicycle=closed way currently
tagged on the whole map.

The other subtler problem is that it might be possible to
confuse"bicycle=closed" with"bicycle=folded" especially for non-native
English speakers.
