Why? What is this accomplishing? As far as I can tell one of these
patches removes a CHECK line and the other adds back the exact same
check. I guess this changes how that particular construct is modelled?
If so, it might be better to just make this one patch so it's clear that
you're not removing functionality, but changing how it's done.
