Logic error detected!

If I decide to meet with a friend AGAIN in front of Whizzo, we both already
know where it is.

If I decide to meet with a friend next year at somewhere we have never
been, the Whizzo
restaurant and it's now a motorcycle shop, maybe it's better we know that
Whizzo no longer
exists than we both decide it must still be a restaurant because old_name.

I take your point, though, there are edge cases either way.  But I also
recall you saying that you
primarily used old_name for the benefit of other mappers, to prevent them
making changes
based on outdated information.

So old_name isn't useful to people using those tools, anyway.  Which means
there's no
reason to use old_name instead of note.

I'm not persuaded it's useful to use old_name the way you do.  Particularly
when old_name
merely indicates a change of name but note=* can be used to also say why
the name changed
(such as change of use).
