I don't think it's really needed. Installing paper into ADF is a
physical action. I don't think user needs a confirmation from computer

BTW, some users missing push-mode scan, totally missed from SANE. But it
requires the whole image logistics to be rethought: user presses some
buttons at scanner, scanner connects the computer, some daemon accepts
this connection, then somehow GUI popup should occur with a question,
how to handle received image.
It doesn't fit well the UNIX multiuser model. At what desktop this popup
should be open? (unlike UNIX, on Windows current terminal session has a
very special role in respect to other system).
