this is valid for England and maybe Scotland and Wales (and probably
some other countries), but it is not working on a worldwide basis.
Your definition would in most of central Europe not be functioning:
routers would lead pedestrians in areas where they are not allowed to
walk (cycleways). Nobody would tag them with foot=no because it's
obvious ;-) that you can't walk there. foot=yes would be the
exception.

When you write about meaning you should keep in mind that what seems
obvious for you isn't for someone with a different background, but he
might rather think that the opposite is obvious.

don't tag redundant stuff, just highway=cycleway; foot=yes would be
worth a second tag...

Actually I wasn't writing about the best way to tag cycleways.

cheers,
