When you click CTRL+Backspace, terminal emulators sometimes convert the key-press to CTRL+H, CTRL+W, CTRL+?, Esc seq, TTY. Default is set to "none", therefore using default VTE settings and nothing changes unless you manually change it. I recommend CTRL+W. Ctrl + Breakspace Merge multiple vte.feedChild into one. Ctrl+W / H / ?

If one offers an option for Ctrl+Backspace to send ESC [ 3 ~ (delete), ESC [ 3 ; 5 ~ (C-delete) could also be supported as an option. In addition, there are other terminal keyboard protocols to properly represent Ctrl+Backspace:
- In xterm's modifyOtherKeys, Ctrl+Backspace may be represented as
ESC [ 2 7 ; 5 ; 1 2 7 ~(C-DEL) orESC [ 2 7 ; 5 ; 8 ~(C-BS) depending on the implementation. - In the kitty keyboard protocol, Ctrl+Backspace is represented as
ESC [ 1 2 7 ; 5 u(C-DEL). Technically,ESC [ 8 ; 5 u(C-BS) is also a possible sequence.

\u001F is not ^?. \u001F is ^_, and ^? is \u007F (i.e., ASCII DEL).
edit: I think I knew a terminal that sends \u001F (i.e., ^_, ASCII US) for Ctrl+Backspace in the past, but I cannot recall which terminal it was. As for the terminal application side, GNU Emacs and Readline treat ^_ as "undo", which is useful when accessible from Ctrl+Backspace.

\u0007 is not DEL. \u0007 is BEL. I've never seen a terminal sending BEL for a keypress of Ctrl-Backspace.

"threat" should be a typo of "treat". "removing deleting" should also be a typo.

There seems to be some mismatching. SETTINGS_PROFILE_CTRL_BACKSPACE_VALUES[6] is "TTY".

"tty" doesn't seem to be handled anywhere.
