No, this views stuff (geophysics, packed, etc.) do not appear at all in GeoAPI.
They do not appears in any OGC/ISO specification I'm aware of. I don't plan to
bring that stuff in GeoAPI since I suspect that it would be highly controversial
(it is already in GeoTools alone).
This stuff exists only because I try very hard to conciliate two worlds:
- data as floating point values in geophysics space.
- video cards (through Java2D) which work best with
integer values in RGB space.
This is controversial for good reasons, but I try very very hard to preserve the
geophysics meaning of images, otherwise the whole coverage module would become
pointless to me (even if RGB images have a lot of values for other users, I'm
not myself in those fields. This explain why RGB support was poor in the first
place).

Yes it is correct. There is no GeoAPI 2.3 as far as I known?
The pending API change in GeoAPI coverage are about replacing the old OGC 01-004
specification by ISO 19123. This is yet an other topic. The geophysics /
photographic / packed views issues is unrelated to either OGC 01-004 and ISO
19123.

We just created the following page:
http://docs.codehaus.org/display/GEOTOOLS/Improve+support+of+RGB+coverages
but this is just a skeleton for now (we are just starting the work on wiki side
- I admit that this is a very late stage).
