According to the manual page, v.kriging does
handle 3D input explicitly[1]:

"method ordinary kriging extended to 3D"

To this end, it even supports variograms for
3D data (flags '-b' and 'u'), and you can use
both 3D points or a Z attribute as input.

I have not tried 3D kriging myself, but I would
be extremely interested to hear back from anyone
an this list how well this performs!

Best,

Ben
