Yes we are. Both of them need an energy input to account for the
deformation on the scale we are seeing. Differentiation of the Earth
into a core mantle and a crust = the planet's Formation. What we are
seeing = the planets *DE*-formation.

...inscripted in the rotational symmetry of the crustal deformation of
the Earth, which removes it entirely from being a result of internal
indigestion (convection), and which points to it being linked to the
present-day, first-order deformation of the planet, namely its ambital
bulge.

You have to explain how:-
1. without a subsequent heat input, the initial differentiated layering
of the Earth into a core, mantle and a crust (by the dissipation of its
heat) can be upset by 'convection' that has extruded mantle to the
extent of two thirds of the planet, formed mountain belts, and pulled
that differentiated crust apart - and done all of that without any
subsequent heat input.
2. How all the deformation of the crust, which is 'torsional-symmetric'
with the ambital bulge, relates to convection.
3. Why the energy release related to brittle "downgoing slabs" is so
much greater (and the greater the more depth) than the energy release
in brittle transform faults that delivers all this mantle crust to the
subduction zone.
4. Why the ambital bulge exists at all (in a convectional framework)
and what is its past geological expression.

..before you start pointing the finger at mechanism for expansion,
which observation makes plain it doesn't have a mechanism. You're the
'physicist' around here. Who knows, if you start asking some
questions Stuart, you might help people find some answers, instead of
being such a dog-in-the- Plate Tectonic -manger.

All is not well in the State of Plate Tectonics, and it needs more than
your finger plugging the hole.

Your call.
