That's the kind of hand-wave that turns into a CVE later. Network exposure is one thing, but weird signal handling in local tooling can still become a cross-session bug or a nasty security footgun on shared infra, terminals, or jump boxes.

If you have shared psql sessions in tmux or on a jump box one bad cancel can trash someone else's work. 'Just firewall it' is how you end up owned by the intern with shell access.
