I agree here.  Previously we were talking about polls about
unused/obsoletable functions/Lisp files.  Storing those in an
"obsolete" directory or whatever else does not impact general Emacs
performance.

In contrast, unused keybindings hog user interface resources.  A lot
of bindings come from a time where there were few functions yet
available, so one could assign keybindings rather freely to them.
When new, much more convenient and more often used functions get
concocted, there are no easily accessible bindings left.  It would
probably be a stretch to make a connection to major Emacs developers
(like RMS and Ben Wing) suffering from RSI, but I think some
keybindings of Emacs might be worth reconsideration, and this might
require some polling.

We might need something similar to "disabled" commands for
keybindings, so that users get clued in about when some favorite
keybinding of theirs might be replaced in a future version, and maybe
also tell the user when an alternative binding already exists.
