Ben,
As I recall, you did raise the subject, as the Illuminists were using the BBT as part of their argument.
There are not many histories of the evolution of the theory as popular reading today, so what you are missing is that when redshift was originally detected, it was assumed these galaxies were simply moving away in space. Though as they observed more, it became apparent this redshift increases proportional to distance in all directions. The effect this creates is that we appear to be at the exact center of the universe.
Then “tired light” was suggested, that it wasn’t recession of the sources, but that something was slowing the light, making it the variable. Yet there was no evident material to create such an effect. Then it was decided that space itself must be expanding, using the premise of spacetime.
The popular analogy used these days is of the inchworm crawling on an expanding balloon, with light as the inchworm and space as the balloon.
Yet it really does overlook the fact that this expansion is still relative to the speed of light. Lightspeed is considered a basic intergalactic ruler, so what is it measuring, if not intergalactic space?
According to this theory, there are two intergalactic metrics of space. That defined by the speed of intergalactic light and that presumed from the redshift of the same light. The balloon versus the inchworm.
Since the redshift is supposed to be caused by the light taking longer to cross, then the theory is still using the speed as the stable metric, against which the expansion is measured.
Here is the paper I was referring to;

I put a space between h and ttps, to keep the entire thing from downloading.
On an entirely different subject, here is an article on the history of finance being used as a predatory feedback loop, rather than a system of accounting to enable mass societies to function;
Ps,
“How is it nonsense to measure difference by using a constant metric? How else could differences be determined? If everything were chaotic, there would be no order to take as standard or to distinguish from the disorder. Indeed, metrics are constant by definition.”
Basically you are making the point for me. The speed is the standard.
