In the context of scanning negatives and films using high end scanners
xsane is not scanning application but a toy.

I think I outlined this a couple of years ago. Basically the sane api
simply does not have provision to communicate everything required to
talk to even a prosumer film scanner let alone a professional one. For
starters there is no provision for IR channel data, multisample
scanning, focusing, and batch scanning i.e. I have just inserted a
holder with six negatives scan 2 through 4. Or I have just inserted an
APS film please scan negatives 1 through 6 and 12 through 30 while I
have a cup of coffee.

Then we require a front end to deal with all these issues, and all the
other bits and pieces like comprehensive negative colour correction.

However as far as I am aware zero progress has been made on any of these
fronts, even though IR channel provision has made it's way into sub
100GBP flatbed scanners in the meantime.
