I have done some further research on this, and it appears to be a bug of
some sort.  Possibly the Locators are already made by the time the
ax.set_xticks([]) is called and that function falls on deaf ears because the
real xaxis is actually a different object for Axes3D.  When trying to dig
down and force zero ticks from being used (using NullLocator), I get errors
when attempting to draw:
