This actually sounds very interesting... Maybe you could suggest it in
#54074 ...

My idea was actually to have an interface like the one of use-packages
in define-minor mode... for customs (vars), hooks and bindings... so
disabling the mode automatically restores the variables, removes the
hooks and cleans the bindings... But in the background either your
proposal or Juri's looks fine...
