No, I mean with SIMT as well. And increasing the size of fixed-width operations from time to time does not help existing code.

See the shuffle operations and similar, which operate on the parts of the wide registers and which are actually needed for the real life optimizations to avoid expensive memory accesses and allow operating on the registers alone.
