The problem is that I would argue USF has already been on the back burner (certainly quality-wise) for a decade.
IOA, even with a dead Lost Continent, is still the vastly superior park in terms of what's on offer. And it was ten years ago, yet in that decade, it has received three good-to-great attractions (Skull Island, Hagrid's, and VelociCoaster*), with Pokemon on the way.
Compare that to USF, which I'd argue has only added one truly good thing in that span (Bourne), and it's a stark contrast.
* Two of which were also additions, compared to all of USF's stuff being replacements.
