I still think it's a good idea to make this work, but it has to be more efficient. Perhaps a way to implement this would be to make the beginning-of-thing/end-of-thing functions (or something in that vicinity) check whether there's a field in the area it's covering, and then limit itself to that area first. That should fix the performance regressions -- the problem with just calling field-beginning/end without any limits is that it will search through the entire buffer, and that can be slow.
