This was briefly mentioned as a possibility in review discussion on D149369 <https://reviews.llvm.org/D149369>.
One slightly surprising bit to call out - these interfaces can get invoked with non-vector typed arguments. LoopVectorizer likes to call the costing interfaces with scalar types when unrolling, but not vectorizing. I found that surprising, not sure if others do.
