btw, since you're quoting this very interesting article, it has

huddersfield (see latest JAES), who found that there is _no_
vertical precendence effect and that interchannel time differences
in vertically spaced loudspeakers do not contribute to localisation
in any way. helmut is aware of this and has presented a much more
compact 8-channel mic array at ICSA 2015 in graz, where the top and
bottom mics are practically coincident.
Perhaps I've missed it but no-one seems to have mentioned head
movements.
head movements are certainly important, but mostly for horizontal
lateral localisation. you would have to stretch your neck to very odd
angles in order to make use of vertical ICTD, and at the same time lose
horizontal ITD (although the latter might not be a problem since
localisation perception seems to be constant once a suitable set of cues
has been "collected", as long as no contradictory cues show up).
