It's not that big of a deal, to be perfectly honest.
The main reason to import the game -- getting it early -- is kind of moot, because we get it only two weeks after JP. That's damn good. And reverse importation is a pretty big deal for smaller industries, and leads to some controversial but understandable decisions (lol fate/zero boxset). This is one of those controversial but understandable decisions.
We wanted a near-simultaneous content-identical release, and we got it, but we're paying the price for it by getting a region-locked game. That's all there is to it.
