Honestly, the park has steadily eroded attractions over the years that have not been replaced, so I'd argue this is really just a return to the level the park had in the past: Skyway - not replaced, Keelboats & Canoes - not replaced, Stitch - not replaced, Mickey and Minnie's houses - not replaced, Galaxy Palace Theater - not replaced, even if some of these were minor, that's 6+ things off the top of my head that used to exist as attractions and now do not.
If you assume SDMT replaced 20k leagues that takes care of that as far as the FL Expansion, and Ariel's dark ride could technically be considered a replacement for the missing Snow White dark ride. Otherwise, the park has had a lot more losses than gains over the years.
I find it startling that MK has (significantly) fewer attractions than DL.
