This revision now requires changes to proceed.

I'm not entirely sure about this interface.  I see there's precedent in code for working with the branch weights when removing cases, so I see where you're coming from, but the rest of our interface (e.g. branches) don't have an analogous API.

I think that if we're going to add an API like this, it needs to be uniform across all the terminator instructios.  Having it otherwise is just too confusing.
