I'm sure others have explained it more eloquently than that, but usually if something is at WDW but not DLR, or vice versa, it's often explained by the mix of visitors being so different at each park. (It's also why WDW doesn't change their Haunted Mansion and DLR does.) So while I would never count out changes to the reservation system at DLR as Disney is always throwing curveballs, there hasn't been anything on the horizon about it.
As someone who's been more often a WDW passholder over the years, it's been hard not to step in and respond when people see WDW doing something and wonder why DLR isn't, to the point where I almost want to write a pinned post and leave it in this forum. (I talked a little about that kind of thing in the Day Ticket thread - the idea that WDW "got rid of park reservations" almost qualifies as misinformation.)
The thing I'll add to what you're saying: WDW took a much harder beating over the last five years - they have an
insane amount of available park capacity outside of the holidays.
WDW operates more like Vegas - boatload of hotel rooms, boatload of park capacity - fill it by any means possible. The deluxe resorts have a huge amount of convention space, for example, to try and pull that audience in. But, for example, they were hurt by the decline in the foreign tour groups (ie, Brazilian) that would bring in
tons of people. On top of that, a lot of people aren't going to Orlando for political reasons now, some because of Desantis, some because Disney is "woke" now. WDW already got rid of the unpopular resort parking fee that was a disincentivizer (getting rid of that was, quietly, a hotel cost reduction, too) - and we're starting to see more and more discount deals for resorts. They're way more desperate for people to show up.
During the same time period, I think things have been pretty consistent for DLR - it's been mostly insulated. The fact that they're limiting APs this severely just supports that.
