@migeed-z I tagged as P1 for now, but maybe there should just be a P0 epic for variance stuff, it does seem like it needs work in a v1 release

This is a much bigger problem than I thought! ideally, we want a warning mode, a checking mode and our inference mode. This will need additional plumbing so we can reuse as much of the machinery as possible but configure it with different settings.
