--- Comment #1 from Darren Tucker <dtucker at dtucker.net> ---
I don't think this is something we want to do.  At least not as a
%-TOKEN.

 - there's no guarantee that the environment variable will exist at
all.  Currently every attribute is guaranteed to exist, so the
semantics when it doesn't would not be clear (expand to nothing?  leave
unexpanded?  throw an error?).
 - we don't currently do environment variables here and this opens a
whole other can of worms^W environment variables.  There's only so many
letters on the keyboard.
 - ssh and sshd are command line applications not desktop applications.

With the functionality added in #3014 you can construct the path in the
client's config file if you know the scheme it's using (eg
"RemoteForward /foo/bar /var/user/%i/baz") or look it up at runtime and
add the forward using ControlMaster (which also works if you want the
inverse direction, if you happen to want that):

$ echo 'ControlPath %d/.ssh/%C' >>~/.ssh/config
$ ssh -Nf -o controlmaster=yes server
$ remdir=$(ssh server 'echo $XDG_RUNTIME_DIR')
$ ssh -O forward -oRemoteForward="$remdir/S.gpg-agent /foo/bar" server
