I don't think it is mostly just the same CPU with a slight twist. It'd be mind-blowing tech if you showed it to some electrical engineers from 20, 15, shit even 10 years ago. Chiplets were and are a big deal, and have plenty of advantages beyond yield improvements.
I also disagree with stacking not being a crazy advancement. Stacking is big, especially for memory and cache, which most chip designs are starved of (and will get worse as they don't shrink as well)
There's more to new, radical, chip design than switching what material they use. Chiplets were a radical change. I think you're only not classifying them as an "alien" design as you're now used to them. If carbon nanotube monolithic CPU designs came out a while ago, I think you'd have similarly gotten used to them and think of them as the new normal and not something entirely different.
Splitting up silicon into individual modules and being able to trivially swap out chiplets seems more alien to me than if they simply moved from silicon transistors to [material] transistors.
