to me, the tag "old_name" means the old name of what is mapped, a name that
was once in use for this "thing" and is now commonly replaced by a
different "name". If there once was a restaurant Whizzo, which closed or
moved away and now there is an Eatwell, then for me "Whizzo" is not
generally the old_name of the Eatwell (it would be if Whizzo at some time
decided to rebrand itself as Eatwell or it could be if the restaurant
basically looked the same and only the name (and maybe operator) changed).
old_name may be clearer for place names, where it is often not in question
that it is about the same place (e.g. Chemnitz -> Karl-Marx-Stadt ->
Chemnitz couldn't find traces of old_name in this case though) while most
of the restaurant tags refer to the service and operating business. It may
also be useful for subway stations or renamed streets (you may even find
old street signs, especially if they are engraved into building walls they
will typically not be "scratched over").
