The "Does ISA Matter for Performance?" article linked above mentions one of the changes made to the POWER ISA for improving performance. This is the relevant fragment:

Still ISA matters. And even within a family, ISA changes can have a huge impact on performance.

[...]

Inside a mainstream ISA, the trend of the last decade has been the successive addition of small and large sets of specialized instructions for doing various important computations. [...] Power Architecture has included binary-coded-decimal instructions, and IBM mainframes have instructions that do string copies in the L3 cache. Configurable architectures like Tensilica show the value in adding a few well-chosen application-specific instructions. Adding features to existing ISAs has been proven to have very good bang for the buck.

The new ISAs developed by Intel CDI, ERI, PFI are not about doubling the size of vectors, but look for increasing performance in concrete cases. The original AVX512F doubles the size to 512bits, but the new AVX512{VL, DQ, BW} maintain the same 512bits and introduce other features to improve performance in specific cases where AVX512F is not enough.
