It's a bit like squeezing out everything from current microprocessors and other modern technology, eventually you simply reach what is actually possible without going off into ridiculous complexity/cost.
Yeah, it feels like most of the complexity of present codecs is spent on catering to blocks and deblocking.

I think alternative approaches are sorely under-researched. Not much effort was put into wavelets, even less into Daala's overlapped transformation before it was dopped.
