Sorta-kinda. We are, in fact, a long way from the 1960s in terms of electoral participation, economic and social mobility, empowerment and the like, so to the extent this reins in a lot of the 'historical effects-based' stuff (which doesn't really have a definable temporal endpoint and eventually just devolves into naked proportionality as a governing principle), I'm actually kinda ok with that.
Obviously, intent-based stuff is never acceptable, and so we still need VRA. (And of course, the VRA has lots of continuing relevance outside the redistricting context.) My concern with the majority opinion is that it's made it virtually impossible to make out the intent-based redistricting case in that not only must there be 'current' intentional discrimination, but that the plaintiff must 'prove the negative' that neutral factors didn't predominate. Sorta like saying that "a little" discrimination is ok, which is awfully weird and uncomfortable.
(OTOH, flipping the coin, there's a practical paradox here from a state defense perspective as well. Because of the incredible correlation of black voting and Democratic affiliation, which is really unlike anything else in American politics by orders of magnitude, it becomes awfully difficult for a state to "disprove" a racial inference with respect to actions that may in fact be politically motivated. And I am in the camp of thinking that Rucho was more right than wrong in allowing partisan considerations to justify map drawing.)
