Nah, nobody is using it. The other systems we have seen use "mixed" as a
config parameter, but I don't know what they expose.

Unsure... that depends a lot on the user, and GeoTIFF is a different kind
of beast... I would handle it in a different way, allowing
the user to specify what they want like in WCS 2.0, if that machinery gets
built then yes, within that context it would make
a bit more sense to have a way for the user to tell GeoServer to use a
"JPEG or DEFLATE" compression based on whether
there is transparency (but then again, one could argue that in that case it
makes more sense to return a JPEG compressed
image with a binary nodata mask instead... as said, GeoTiff is
complicated...)
