`port list installed`,`port list all`, `port list <specific port>`.

Having commands just because users might try them doesn't seem like a
good policy to me. As for the "we know what they meant" argument, it
would seem that we don't, judging by the differences in what we think
the command should do.

I'm happy for list to be removed. If it stays, its output needs to be
changed so it's clear what it is showing, and so 'list installed' does
something sensible. One possibility would be to have two labelled
columns, one for the available version and one for the installed
versions of each port.
