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 
that paper was actually installed; user knows it by feeling from its 
fingers.

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).
