Dingle's mistake was assuming a direct cause. But it may be that

In physics situations like this arose many times. For example,
Maxwell's theory required equipping EM fields with their own
momentum and angular momentum (otherwise the conservation laws
would fail). Nobody knew what the seat of that momentum was.
This was only modelled much later in quantum electrodynamics.

It's very likely that time dilation, etc., are similarly conditioned

Same thing happened with thermodynamics when people started to

heat was, or even at one point while having the wrong model of
heat (the "caloric" or "phlogiston" model).

confusion of physics with philosophy.

This is perceived a remarkable recent timidity, from what
was earlier your expressed "very SR-ian" opinion.
Reflecting "chaleur and the caloric" with "a-diabatic and
non-a-diabatic", has that Fourier is surely great and all
of analysis sits on its examples, while as well any sort
of difference from the "one-way" model, or for example
any sort difference in the formalism the interpretation
of uniqueness of the Fourier series, does reflect on
that the Laplacian is _partials_ (incomplete).
The "photon" its definition has been so diluted and overloaded
that its relevance to measuring and defining velocity,
has broken the metrics and norms in most all extensions.
Then, it's perceived your more sober assessment is improved,
than before your so-correspondent estimation of "truth",
regards these matters.
The physics and philosophy with regards to theory and metaphysics,
are a combined notion, for a "the theory of truth" and for
as d'Espagnat puts it a very "realist" theory, of a "the physics".
Classical motion itself is under-defined. This "unstated assumptions"
or "hidden implicits" or what make "supplemental variables" when
"hidden variables" were put down as negligeable, these
"zero-eth laws" help show that physics is more than absent philosophy.
