Just to add another data point, I have a customised Mapnik stylesheet
that I use on my websites that replicates the OS style of having the
right of way overlay the physical nature.
For tags of {foot,horse,bicycle}={designated,permissive} on anything
other than highway={path,footwa,bridleway,cycleway} an overlay is
drawn using either a footpath, bridleway or cycleway style.
Description:

Example:

If we could modify the default stylesheet then we wouldn't have to
worry about tagging for the renderer on these highway types. An OS
map can be used by walkers, horse riders and cyclist to plan routes
but the default OSM stylesheet produces maps that cannot be used for
this.
For the question about whether highway=footway, highway=bridleway and
highway=path are redundant my vote would be that they are overlapping
rather than duplicates. A highway=bridleway should be assumed to have
no obstructions in it that would stop horse or bicycle traffic while
a highway=footway may do.
