No, this particular problem generally does *not* cause accidental
deletion of relations!

The worst that can happen is someone splits a way and does not add the
new part into the relation (because he does not know about it). Then a
multipolygon is no longer closed and does not render ... something like
that.

Also, if the user operates inside the downloaded bbox, everything is
fine. The issue comes into play when editing boundaries and other large
scale objects.

Then, I'm not so sure if one of the main editors should depend on a
private third party server, to operate properly. (It may also generate a
lot of traffic for that person).

Another drawback is the delay. JOSM users are used to getting their data
in real time. It is a little hard to communicate: "You will always see
all parent relations in the list, *but* the object and the relation have
to be a couple of days old (and a certain server has to be accessible)".

So from my point of view it would be great to have a plugin that uses
this service, but for JOSM core we should try to get this working
working with the main server.
