Can you point out the wiki part you mention? I do not seem to find it. bicycle=dismount seems legit here.

In Quebec, bicycle access is prohibited by law on all sidewalks, except when permitted with a specific sign. Thus, by default, it should be dismount. Park footpaths are ambiguous, but we usually tag them bicycle=dismount except when part of a cycleway network or when bicycle pictograms can be found. Some routing engines now block access to bicycle when bicycle=no even at walking speed (dismounted), so it is  safer to not cut access to parks to bicycle routing engines and keep the bicycle=dismount value.
Thanks and have a nice day!
