Except total unaltering is impossible you can put the big history book events back into place (ie zefram cochrane invented the human iteration of warp drive) but the butterflies are still set loose (ie zefram cochrane was told about the enterprise-E by time travelers and was shown it through a telescope in order to gain his trust and cooperation, a century later a hitherto unmentioned ship of the same name and rough silhouette would be launched supplanting Dauntless as the name associated with the NX-01 registry.) Our time travelers don't notice the differences when they return home because they are so far removed from the altered events that the fog of history essentially covers things up.

You're moving the goalposts asking for such explicits beyond what is reasonable. Why would they need to spell it out for you in an interview when they have the actors say "these events weren't supposed to happen" repeatedly on screen? Are all viewers expected to familiarize themselves with every entertainment news article around and about a film or TV show in order to understand it? These things should be intuitive, and if what is intuitive isn't the writer's intent then that's just a failure on the writer's part.

This timeline is Altered not Alternate They did the same thing for First Contact, and ENT add just enough time travel to excuse not making the show into a history documentary yet none the less its considered part of the same story as everything that was made before but came later in the timeline.
