I think the future is exactly what a lot of fans seem to want: Forget worldbuilding, just throw an interesting story onscreen using some recognizable Trek things like transporters and phasers, no extended Trek story spanning several series, no need to specify a timeline, it's all just stuff in space with the Star Trek name on it..
Works for me.

Seriously, it's worth remembering that not every fan watches STAR TREK for the same reasons or with the same priorities. I get that some fans are all about the "world-building" and the overall future history, but for others that's just the backdrop to whatever individual story is being told in the foreground. They may be more into the hardware, or the characters, or social allegories, or inspirational messages, or whatever. They may love TOS and ignore VOYAGER or vise versa. They may be fascinated by Klingons, but feel no urgent need to revisit the Bajorans ever again.
And that's fine. There's no "right" way to watch STAR TREK.
In short, providing an "extended Trek story spanning several series" is not necessarily what STAR TREK is to everyone.
