It's what they should've done, but they didn't. The intent was that it was essentially the same prior to 2233. That's clear enough from Beyond. Despite the way some people blow a few tiny inconsistencies with Enterprise out of all proportion, the fact that the movie builds so much on Enterprise concepts at all -- the MACOs, the Xindi, the Franklin's ship and uniform designs, etc. -- is proof that Pegg, Jung, and Lin wanted their movie to build on the existing pre-2233 continuity, not divorce themselves from it completely. As I keep stressing, the idea that things could change pre-2233 is just a handwave for minor discrepancies when needed. The storytelling intent is very clearly that the two timelines were essentially the same before Nero, even if a few minor glitches get through here and there.
After all, if they had done a from-scratch reboot, there would've been no need to build the first movie around a convoluted time-travel premise to justify its differences.
Yeah, but it's a complete waste of the potential of a full reboot if you just use it for minor, insignificant changes like that. What a gross failure of imagination that would be if it had been what they'd done. A full reboot is an opportunity to reinvent everything from the ground up. To give characters different genders and ethnicities (something the white male-dominated TOS cast would've benefitted from), to change the timeframe and history to something that builds off of the present rather than 50 years in the past, to amalgamate ideas from different series, etc.
I always thought the genius behind Star Trek (2009) was that it didn't really meet any of the standard definitions of a reboot or prequel, but combined those elements and that of a sequel even. It allowed them to 'reboot' Star Trek without actually 'rebooting' it. Having Ambassador Spock in it was really the linchpin. It allowed them to have their cake AND eat it too. It gave them a reason for making changes they wanted to make while still saying they're not forsaking all that came before in canon, that it all still happened. I had some complaints about production design, but story wise I thought it was pretty incredible.
As for Beyond, I saw more consistencies with Enterprise then inconsistencies. I can nitpick with the best of them, as most will attest to with my comments. But overall I thought the Franklin fit quite well with the continuity established in Enterprise (except for the stupid window on the bridge--would it have killed them to put in a viewscreen on the Franklin at least, sigh). I picked up on the transporter comment about not being rated for human use, but like some others I figured not all Starfleet ships had top of the line technology. In fact we've seen that on Star Trek before, where co-existing ships are not equal in technology.
As far as the comment about the Xindi and Romulan Wars, if just thought he was using the plural because they were two different wars (sort of like saying the Korean and Vietnam Wars).
I just watched the Enterprise episodes "Stormfront" and found it interesting when they were discussing when the time changes began, how they began with Lenin being assassinated which was before Vosk came in the picture. It was a mystery that was never really solved there (except with a line about another possible faction interfering in the past). Could changes in the timeline ripple to the past? I thought Enterprise left open the possibility, and Nero's incursion also might lead credence to the idea. In reality though, I figured everything pre-2233 was left intact and any changes we see mostly due to artistic license. I thought the Franklin and it's crew were close enough that any differences were largely negligible. Now the Kelvin's design is a bit more hard to explain away with simple artistic license. But I'm sure if this impasse with the novels is ever resolved one of our resident novel writers could probably create a story to explain that in a way that fits with existing canon
