Thank you for the clarification.  I have a better rational for your change;
"user agents" appears repeatedly in the specification; "client applications"
occurs only in this specific paragraph.  The other rational alternative is
to drop the word client.

Remember that an application/user agent may not even be interactive, and may
be an application with a preferences.conf file which can be configured
appropriately.

You presume.  Let's say that in your example above that as TOR's outbound proxy,
an assortment of proxy services are offered, e.g.

http://fr.tor.example.com
http://dk.tor.example.com
http://en.tor.example.com

I can make the rational argument that these three are user agents acting on
behalf of the endpoint user agent, even with the language change you propose.

Of course.
