Is it impossible to change the parent of an existing subsurface?
If it is possible then A<B<C and attempting to change B's parent to C will produce a loop and not get detected by this test since get_main_surface(C) is A which is not equal to B.
If this is not possible it seems pretty limiting as clients have to destroy and recreate surfaces to make some rearrangements.

From: Pekka Paalanen <[email protected]> The only way to create a sub-surface loop by recursive nesting is to make the main surface (which does not have a role) a sub-surface of any of its sub-surfaces. All other cases should already be cought.
