[Tagging] Footways where pedestrians may only walk in one direction: oneway:foot=yes or foot:backward=no?

[Joseph Eisenberg]

Some paths and footways have oneway=yes. Sometimes this means that
bicycles may only access these features in one direction, but other
times it has been used for one-way features for pedestrians (for
example, queues in theme parks or at border control stations).

Other more specific tags have been promoted, since the wiki states
that oneway=yes is for vehicles.

https://wiki.openstreetmap.org/wiki/Key:oneway:foot is used about 1400 times

https://wiki.openstreetmap.org/wiki/Key:foot:backward is used about 140 times

The wiki for Key:oneway was just edited to recommend using
foot:backward instead of oneway:foot

But as an English speaker, I find it difficult to immediately
understand the meaning of foot:backward=no (which uses a double
negative, as it were), while oneway:foot=yes seems clear right away.

Is there really a reason to prefer the less common tag? Does it make
more sense in other languages?
