Window title handling change in PuTTY 0.78: unresolved decision on title restoration after exit

PuTTY 0.78 defaults to SSH‑2 only and retains the existing “Set by server” window‑title behavior, which leaves the original title unchanged after a session ends. Users who want the window title to revert automatically must currently rely on an undocumented registry tweak or third‑party patch.

Changing the default or exposing a GUI option would affect scripts and terminal multiplexers that depend on the current OSC title handling, creating a compatibility boundary that needs evaluation.

Should PuTTY add a GUI option to restore the window title on exit? Would altering the default behavior break existing workflows that rely on the title persisting after disconnect? Is there a safe way to introduce this feature without interfering with terminal multiplexers or scripts that expect the title to stay set?
