Not really, but there are not much programs which are primarily run over
SSH forwarding I know either.

If one really wants an active warning one could do a check like:

defined($ENV{'SSH_CONNECTION'}) && !(-x /usr/bin/xauth || -x /bin/xauth)

A bit crude but could work, and could be used to print out a early warning.
