The problem is that it is plausible that some people may be mistaken
or invent a new use for that tag and tag something.

Making this key discardable would result in silent removal of that.

Silently deleting for example osmarender:nameDirection is OK
because there is no real scenario where mapper would use that
for anything useful.

For "history" tag this assumption would not be true.
