It's unclear what that's supposed to mean. There's obviously still a
transport involved; in one case, that's over (I presume) TLS over a TCP
connection owned by drawterm, in the other, it's a bitstream running over
the SSH protocol over TCP. In the former case, if the drawterm process on
the Linux side dies for whatever reason, your imported resources disappear.
In the latter, if the sshd or u9fs die, same.

Overall, this seems like abusing drawterm to do what u9fs (or other,
similar userspace 9P servers) was (were) intended to do.
