I think you taught me a though lesson, thanks.
Indeed, nothing to compare to what I've gone thru when, in 2016, I tried to come up with something new on SR... sacrilege!
Except for a topologist in Bononia, who spent some time trying to understand my point, and maybe Rovelli too, nobody would listen... A topologist, one that doesn't care for the measurements and metrix, helped me with semi-norms, that's what spacetime distances are... I'll come back, that was not BS!
It didn't end up well with me, I'll spare you details, but when I saw my question blocked for no meaningful reasons... not again please no!
Then your reasons became increasingly meaningful, while the underlying hostility didn't go away.
I'd have dozen of question to ask on both the representation and the map, as to me they're related: what's the model behind Planck's units? or at least the interpretation he tried to give? I recall about orbiting photons... Of course I have another model, and a set of units whose "regular matrix" is not an I, but is full of $\pi$s on the diagonal. Let alone this model fits perfectly in the map, explaining the apparent "broken symmetry" there... my Galois-Noether conjecture is approaching fast!
But now I know this community is only to ask straight questions like "are there upper and/or lower limits to frequency values, for photons?", without any details in why I might be interested in that. I'd feel sorry for you, doing so!.
For some more constructive work, I'd go for HSM, where I already got something quite good done, not to mention those people do not have neither these obsessions of yours (with a rationale, but still annoying), nor that "here comes the inquisition" approach.
