If we do that we should do it for all the parameters, no? So not just
host:port, but something like host:port:secret:identifier? Mixing the two
ways of doing it would be quite confusing I think.

And I wonder if that format wouldn't get even more confusing if you for
example want to use default ports, but non-default secrets.

I can see how it would probably be easier in some of the simple cases, but
I wonder if it wouldn't make it worse in a lot of other cases.
