Dunno, for me this is like the debates over 28 ga versus 32 ga--I don't have a dog in the hunt.
All the bottlenecked 30s had their place in the sun, if places that were hard to tell apart, one from the other. And, those runs were so definitive, we saw the 357sig try and refill the niche.
Then, we recently saw the 30SC, which is basically a more modern 8mm french long (briefly seen about a century ago as the 32pedersen).
Nearly every caliber has been made, once, at least. The "reasons" for each of them will get revisited, after enough time passes.
Frankly, I'm sore surprised no company has trotted out an 11x25 or 12x20, ignoring that the 11.3x23 has been around for at least a Century (longer if we squint a bit and see it as an outgrowth of the 45 schofield).
