How do you define "commands used in the current buffer"?
. are commands in the minibuffer when Emacs prompts considered to be
"used in the current buffer"?
. are commands invoked from the minibuffer via M-x considered to be
"used in the current buffer"?
. what about commands that switch to temporary buffers and enter
recursive edit there?
. what about commands that switch to another buffer in the middle of
typing a key sequence?
. etc. etc.
IOW, I don't understand how this hypothetical feature could work in
practice, let alone how to document what exactly it produces. Emacs
commands are by their very nature "global", unrelated to a buffer.
