Most canal footpaths are now genuin footpaths, but some are still just permissive. What footpaths allow, and what has a legal basis to go there is different. A path may be a highway=footpath, but horses=permissive, but that doesn’t make it a bridleway. Highway=track doesn’t exsist in the UK though, the track is just a phisical thing, so I’m against the use of this tag.

In short, there is currently not a complete enough tagging scheme to really tag these toepaths correctly, so where I have added them, I am currently using some tempory made up tags to fix the problem.
