I don't understand your sentence. I just mean renaming option in
backend, change some option type. That is mostly a matter of
implementation.

If you don't want to extend SANE 1 standard (like e.g. 1.2), just
provide a RFC for backend developer in order to have backend consistent
and sensor usable by frontend, without end user interaction to assign
sensor to action.

Currently, SANE backend sensor implementation mean : "Something  happen,
guess what". E.g. plustek backend provide "button 0" to "button 4", both
integer with value 0. Once a button is pushed, value is 1. How can a
frontend know what does mean "button 0"=1 ? Can guess "button 0"
pressed. But what next ??

We definitely need semantic in sensors.

Étienne.
