    More specifically:

    footway.

No. There are thousands of footways with
bicycle=yes|official|designated to make them mixed foot-cycleways

Sure, there are many footways with allowance for an extra sort of
traffic, most commonly bicycles. If these footways are tagged
oneway=yes, I'd expect the other kinds of traffic to follow that rule
too, unless overridden with e.g. oneway:bicycle=no.


      - I would also expect a oneway=yes tag to apply to foot traffic on
    pedestrian, path, and cycleway -- unless explicitly nullified with a
    oneway:foot=no tag.

I don't understand the "No." Nothing I wrote precludes using these ways
for both foot and bicycle traffic.

Cycleways are primarily for bicycles, so I'd expect a oneway tag on a
cycleway to primarily describe the bicycle traffic. If foot traffic is
also permitted on a oneway cycleway, I'd expect it to follow the same
oneway rule, unless explicitly overridden with a oneway:foot tag.

Pedestrian and path are a little more ambiguous, but again, I'd expect
the oneway tag to apply to whatever the predominant traffic is. And if
tagged oneway, I'd expect that oneway restriction to apply to foot
traffic unless overridden with a oneway:foot tag.

I'm not *advocating* for this to be a rule -- I'm just describing how
I'm accustomed to interpreting the existing tags. As we know, the
documentation is imperfect. If there's a better way of doing this,
great! Let's document it.
