This is in the mainline kernel since v5.1-rc3:
9c38f1f04408 ("kconfig/[mn]conf: handle backspace (^H) key")
Quoting the commit's log:
"
Backspace is not working on some terminal emulators which do not send the
key code defined by terminfo. Terminals either send '^H' (8) or '^?' (127).
But currently only '^?' is handled. Let's also handle '^H' for those
terminals.

Subject: [PATCH 23/23] kconfig/[mn]conf: handle backspace (^H) key
|
|
|
|
Backspace is not working on some terminal emulators which do not send the
|
|
key code defined by terminfo. Terminals either send '^H' (8) or '^?' (127).
|
|
But currently only '^?' is handled. Let's also handle '^H' for those
|
|
terminals.
