Now you are getting it! That all stopped for Disney owned parks plans moving forward post Everest in 2006, Mission Space was 2003. Your more recently are my 20-30 year ago of how the mandate has progressed. and instead of being a balance, has gone Iger bonkers. Not overly reliant. Subjectively only at this point to where even the bears have to sing A Whole New World and Frozen songs.
The new hub concept was brought up pages ago as not being original. But if we are being fair, it is and I think your description is oversimplifying a bit. Concept art is just that, but now that we see fly overs and see what is going in, it is a bit more than you disingenuinely described. Not peak design, but certainly superior to Mickey Ave, or the EPCOT plaza redo. It has unique and detailed architecture throughout with scenic. It has a backstory of inspiration for the parks throughline.
And Disney has not built an original land or attraction since 2006 be it retheme or new build.
Besides Tiki Room, what near that scale or larger has been original in the states since Expedition Everest? I could be forgetting something, but is totally that dire to where we can realistically say they are not doing an original IP-less land, that would even be on Celestial Gardens scale.
Universal has, for better or for worse, built original attractions and lands since Disney stateside and some overseas.
