Oh, nice. So eventually it'll be added.

Correct me if I'm wrong, but the reason for this absence is that people could think that doing repeated bisects using keys would be fast, even though keys has to be recomputed?

I think that could simply be fixed with a "Note:\Warning:" on the documentation.
So that you can create keys with caching or use precomputed keys when you have to do a lot of bisects.
