We're in this mess because corporate doesn't want to spend money on expanding attraction capacity, and hasn't for years.
Without RnRC, DHS is down to 8 rides operating. Many of which have height requirements or aggravate certain health conditions. Beyond the added operational stress for the remaining open rides, the park still doesn't have enough rides to appeal to all age groups equally.
AK is in a similar boat with EE's extended (if much needed) refurb. 7 rides left open including the Wildlife Express Train and Triceratops Spin. Once again, many of the rides that are open have conditions that may limit certain guests, or simply may not appeal to everyone.
It's clear from park expansions at HKDL and WDSP that Disney knows they've run out of excuses for not building things. They know they've hit a wall with capacity, made worse by the push for line-skipping programs and have reluctantly started to build again.
But we're still playing catch up from so many years of not building things and sometimes, like with TRON, a new build just ends up replacing something else that was closed with no replacement (Stitch). With Disney's inflated development costs and prolonged construction timelines I can't fathom how much time and money it would really take to properly address this problem.
