So the answer is "yes"

Patches welcome.

No. The problem is not that 127.0.0.1 isn't reachable (it always is),
but that *by talking to 127.0.0.1*, OpenVPN does not know what the
"real" jump server address is (that OpenSSH etc connects to).

So OpenVPN needs a host route for the server that OpenSSH is talking
to, but since there is no talk between OpenSSH and OpenVPN, the latter
doesn't know what to do.
