Imo, this shouldn't be considered in isolation. There's a whole lot of
situations where the value for a key, such as oneway, maxspeed,
maxweight, access, is different depending on vehicle or other conditions
- a common example is maxspeed:hgv (note that nobody is using
hgv:maxspeed). And it's a bad idea to create a different solution for
each of these.

There is a concept that covers all of these and uses oneway:bicycle:

The bicycle:oneway variant, to my knowledge, hasn't been part of a
solution that can be used to express all of these cases yet and is
mostly just there as a solution for this single situation (opposite
traffic on oneway ways). Imo, that's a too limited perspective.
