SUMMARY

Neovim implemented the protocol in 2015 by using libtickit:

There are also at least three other protocols for "raw keyboard" input in terminals.

iTerm2 protocol
https://gitlab.com/gnachman/iterm2/-/issues/7440#note_129307021

Windows Terminal's "win32-input-mode"
https://github.com/microsoft/terminal/pull/6309

far2l terminal extensions
https://github.com/elfmz/far2l/blob/master/WinPort/FarTTY.h

The only one of them that already have some support in apps is far2l's one (apps supporting it are "turbo" text editor, "putty4far2l" putty fork, cyd01's "KiTTY"). It is tied to Windows keyboard codes, but translation from x11 codes is easy:
