Making subtle changes to the library behavior, ie. "slight
deviations", is a slippery slope that quickly goes downhill.

I think many if not most users would be thrilled to start using a new
API in order to gain performance, even to the point that it would
quickly become the de-facto standard way of using the library.

I think it's important that we not change semantics, even if it's
only slightly. I expect it will come back to bite.
