It solves your concern over a damaged fuel return line, I assume you are thinking of an accident scenario where your return line would uncontrollably spill fuel from the tank to a firewall forward location?
A simple check valve at the tank would take care of that with no pilot action req'd.

Default I use a Tee…

I have a -4 line that passes the firewall out of the way near the brake reservoir then down through the tunnel to a -6 tee with a -4 adapter in the feed piping near the co-pilots seat… never an issue for me. There is probably a small amount of air introduced here and there to equalize the head pressure when the line is dead headed but it is small and has never been an issue.
