Perhaps the 'user' in 'user agent' refers to the trust model.
So, a user agent would be a program under the control of John Joe,
while a server is usually an application run by a company, or
administrator with responsibility.

In that light I can understand why 'user agent' would be broader
than the term 'client application' or visa versa: a user application
that also allows others to connect to it is also a server. While
a client application can in theory also be a service running
on a secure company network.
