I wonder if the veritable concept of a 'watch' could help minimize this
unfortunate chain of events. The svn mv or svn rm commands could make a
server contact and notify watchers of the repository via email when they
take place (prior to commit) and then you would at least NOT continue
working on the file in question. Maybe something as simple as:

%svn watch -m mjs@jhu.edu executed in the working
copy or
%svn watch -m mjs#jhu.edh URL to get email notifications of
activity on a repo that you may not even have checked out.

We could place our email address(es) in our ~/.subversion/config file
and then not even have to specify the address. Obviously, the companion
svn unwatch would also be necessary and the repo would just keep an
unversioned property with all watchers.

It seems to me that copy/modify/merge is always going to have issues
that require timely communication and watches would be a helpful
communication device.

I know watches have been discussed before and dismissed but I think it
fits very well as mentioned as an aid to team communication.
