UPNP and STUN are complementary (actually there's NAT-PMP too).
UPNP/NAT-PMP would be much simpler to implement in the Psi codebase as it
stands (really it's just the extra firewall call to establish the external
IP address, and map the port to the local machine).
Adding STUN support requires Jingle-FT, which probably requires more code
changes, so I really see UPNP/NAT-PMP as a quick win stop-gap until we have
full Jingle-FT support.
On a side note, you might find that someone implements a symmetric firewall
which STUN can't get around. In this case you'd have to have some sort of
UPNP/NAT-PMP protocol to ask for a port to be opened and forwarded to the
