From that point of view, we'd wrongly conclude

we would observe the Earth from a Pioneer
probe as orbitally decaying toward the Sun.

No, following your "model", the Sun and all the
planets you are passing also are anomalously
accelerated away from you (Sunward).

That's what I said, an anomalous acceleration
toward the Sun.

Dude, did you read what I wrote? The Sun is acclerating away equally
fast. How can the Earth "orbitally decay towards the Sun", if the Sun
is also accelerated away?

Well, there is a point called barycenter. We would wrongly
deduced from that Doppler effect that both the Earth and the
Sun are decaying toward solar system barycenter.
