Because there is no one point at which that could be displayed, just
several different map editor programs, each maintained by different

Perhaps it would be good to have in the database a way of making a tag
as "deprecated", that editor software could read dynamically, but then
it would be stuck if something it assumed was available became
deprecated, and its programmers would have to intervene after all.

And also, there are several renderers (some with multiple stylesheets)
which can each have different rules about what to display and what (by
not having a rule to display it) to ignore.
