This isn't a new phenomenon. I remember riding Pooh's Hunny Hunt in Tokyo in 2002 and just being blown away at what a modern dark ride could be.
Then they opened a Pooh ride in Anaheim which was old school in it's use of simple technology. What a let down.
The disparity between what they're doing overseas vs. in North America has been disappointing for decades.
You will get Rattatouille and Mickey's railway, both the same ride tech as Hunny Hunt.
As to "why won't they build these cutting edge dark rides!"
They are. And the complaining is non-stop and incessant. The new Energy replacement: Cutting edge dark ride. Totally new ride system in fact. People gripe. They want outdated tech and 30 year old animatronics.
We get tron.. people gripe. They want another boat ride full of dancing dolls.
We get Mickey and Minnie's runaway railway (or whatever it is called) and people complain because a horribly dated Energy clone, in which half the effects don't work anymore goes away.
I don't think Pirates or HM can be retrofitted to those newer ride systems. And someone will burn the park down if they scrap either of those rides and replace them with a "knockoff" of another park's ride.
The most we can hope for, realistically, I think, is some new IP or concept (and face it, both HM and Pirates are IP now, just as much as any Pixar character), that is unique to Florida AND embraces the newest ride systems.
At some point, I think Florida became the "we aren't doing anything new and different here, because we have four parks here that are different. So you get clones of other places". That may be starting to come to an end. Time will tell.
