I think we don't need so much detail about the obstacle. If it's light
vegetation, then it's not much of an obstacle, but this proposal
doesn't bother me as long as it's optional.

This kind of scheme never gets used other than by "extreme mappers"
(usually just by the person who made the proposal). I say forget it.

I don't think we need it, but if we have it, the first proposal sounds ok.

I like to keep tagging as simple as possible, and vegetation as an
obstacle has a lot of potential to change frequently. Ever seen a corn
maze?
