[GRASS5] GRASS 3D features query

Hello developers,

I'd like to query for the current status of the 3D
characteristics/features/capabilities/objects implementation... Are
they finally usable? All the documentation I found is

    * face: a 3D area
    * kernel: a 3D centroid in a volume (not yet implemented)
    * volume: a 3D corpus (not yet implemented)"

"[...] Face and kernel are 3D equivalents of boundary and centroid,
but there is no support (yet) for 3D topology (volumes). The only
current use of face is possibility to display vertical planes in

but I prefer confirmation that this is not a problem linked to
outdated documentation. In fact, searching for references to these
objects in the source code (CVS feb 20th, 2006) throws me a few

$ find . -name "*.[ch]" -exec grep GV_VOLUME {} \; | wc -l
$ find . -name "*.[ch]" -exec grep GV_KERNEL {} \; | wc -l
$ find . -name "*.[ch]" -exec grep GV_FACE {} \; | wc -l

Finally, is there any roadmap where the approximate data/versions for
the future GRASS capabilities could be looked?

Thanks in advance,
