The reason that I implemented rotate3d and pan as axes properties was
because of subplots where the user might want to pan in one plot and
rotate in another. How does Matlab behave with subplots, especially if
there are mixed 2D (where rotate3D should be disabled) and 3D plots?

I haven't used classdef yet so I can't make a statement on this.

Do you want to make pan also work on figures or exclusively? We could
make pan and rotate3d make also work on figures by iterating over all
axes children except legends.
