Some scanners require loading firmware and for some this is just
a question of adding identifiers to configuration files. I know
nothing about your scanner so I cannot give you a specific advice.
Look at various files in /etc/sane.d.

It does, provided this is '--depth' and not '-depth'.  The catch is
that this is among "Options specific to device" and 'scanimage -h'
will print that only when it will find a device and its driver.
With that particular scanner I have around it shows

    --depth 16|14|12|8

among many other "specific" options.  If I will use 'epson'
instead of 'epson2' driver, which is possible in this particular
case, then available depths are reduced to only 16 and 8.

That would be likely undesirable and hopefuly nobody will take you on that.
OTOH see https://bugzilla.redhat.com/show_bug.cgi?id=383131
and a discussion there.  That script was obviously meant for a
customization but the last time I looked there, and this was a while
ago, that was not done in a very thoughtfull manner.
