I actually see it the opposite way.
Treating the SNW Enterprise as the TOS Enterprise isn't about conformity, it's about preserving the original creative intent. The TOS Enterprise looked the way it did because of the limitations of 1960s television production. SNW isn't replacing that design with something safer or more conventional, it's using modern tools to visualize the same ship and the same world in greater detail.
And that's coming from someone who absolutely adores the original Enterprise. It's my favourite version of the ship. I love everything about it, but I can love that design while also acknowledging that it's very much a product of the 1960s. The painted backdrops, blinking lights, and plywood sets were never the point. They were the best tools available to convey a futuristic world to the audience of the time.
If anything, insisting that every button, corridor, and visual effect must remain frozen exactly as they appeared in 1966 seems more restrictive. The imagination was always there. We just have better ways to represent it now. To me, SNW isn't replacing the Enterprise I grew up loving. It's simply presenting that same ship through a modern production lens, much as TOS itself would have done had it been produced today.
