I understand the reasoning, but what mappers see now is:

That is, to put it mildly, quite confusing, not to mention
disheartening. It will also result in less-involved mappers remapping
the damage by turning hedges into scrub on the map. The only
alternatives are redrawing them as linear features (losing detail in the
process, and feeling like a massive waste of time) or removing them
completely.

Surely we can come up with a more constructive way forward?

Keeping the rendering for `barrier=hedge` plus `area=yes` for the time
being seems sensible and in keeping with the general use of those two
tags in combination.

If a tagging can be agreed on that can work for several applicable
barrier-values mapped as areas, then that can gradually replace the
`area=yes`-way for hedges. At some point the rendering for the old way
can be turned off to help mappers migrate, but there has to be some
overlap in time.
