I don't quite understand what you are trying to get at with the question,
but let me list a few places where I think bicycle=dismount is implicitly
encoded:
* footways;
* "road closed" (unless certain extensions are added below)
https://commons.wikimedia.org/wiki/File:Estonia_road_sign_311a.svg
* within buildings (train stations, subway stations - you are free to carry
your portable bike around here);
* one way streets from the wrong way (should push either on the sidewalk if
it exists or on the road).

Maybe I didn't make myself clear in that sentence. I referenced a statement
from a different tagging thread a few weeks ago.

The gist is that if a mapper encounters a given tag (like
bicycle=dismount), a given definite meaning should be understood. This may
be _refined_ by further tags on the same POI, especially subtags, like
highway=service + service=driveway. Meaning shall not be redefined, rather
made more specific in these cases. However, I can't say that
highway=service + not_really_service=yes, i.e., a certain combination of
independent tags may not carry a meaning that greatly contradicts with any
subset of the said tags.

For example, bicycle=dismount should be understood that bicycle access is
only allowed if a rider dismounts. However, if we had to write
bicycle=dismount + foot=no, then the meaning basically becomes: neither
riding your bicycle nor walking is allowed here, which is quite the
opposite compared to what bicycle=dismount would mean if it were placed
alone on the POI. Hence the correct way to tag this should be bicycle=no +
foot=no.

I really enjoyed Phil's joke and I recommend that you think about it as
well.
