The chance to deconstruct "Roddenberry's Vision" actually makes the politics angle kind of interesting if they go this way.
This part right here. This is the problem. Because it's not an interesting angle for a show - it's the failure to "get" Star Trek. And sadly, this is the direction the franchise has taken as a whole in the last decade.
Sure, GR's vision was anything but perfect. But that was kinda' the point: A lot of it was left blank to leave room for interpretation or actual real-life developments to be included.
And yes, refining that vision is perfectly fine! As is the one or other episode trying to find the edges and holes of said vision (greetings from DS9). But at it's core - the franchise simply can't be in a constant conflict with GR's original vision! That simply destroys what makes this IP unique.
Imagine if every MARVEL-movie since 2008 was mainly interested in subverting or deconstructing Stan Lee's original ideas about superheroism?
That would have destroyed the superhero genre!
