No. But we can ask the users if they would like the --return(-file) to
mean: Return a file if it is there, otherwise do nothing.

I understand your problem, but do not see the option as generally useful.

It is unclear to me, why you cannot simply do a 'touch outputfile in
the remote script'.

This way you would always generate an outputfile, and if it is empty,
you simply ignore it.
