Seems there are a lot of people jumping to it; just recently I saw a
case where a very young well meaning mapper (20 edits) was named this
way.

You got the point. I am sorry I assumed it would be so clear that there
wasn't need to write a novel about it. :)

That's possible, but it does not solve the problem of the useless tag
(who would go around and enhance 57k imported objects "by hand) but adds
another: the occurrence of this tag could also mean that someone merged
objects carelessly. Dropping this tag silently would make it less
likely to discover this error.
