well... the "problem" is that @@(opt) is already in use since two
years or so. I would find this a good incident to use that format.

You could always use

*.* @@(mode=tls,whatever-else)

The advantage is that a lot of people already know what it is. And
this format is not only available on BSD, but on other platforms, too.
It is the default on Red Hat Linux distros for example.

But... using @T/@U is not really a problem for me, the parser is
quickly adopted to understand yet another format.

The bigger question is how you intend to handle the authorization
issues that come along with -transport-tls. For example, how do you
specify the remote client names that a sender is permitted to listen
to. Or how to specify if you use name, fingerprint or anonymous
authentication. The current rsyslog approach works, but is ugly.
