While the op does not have explicit operands, the op is actually implicitly capturing SSA value, which counts as operands to me.
However it does not just forward its operands to the parent, since it relies on its body to form the actual values to yield (in a non-trivial manner).

I don't quite see what's broken in terms of control-flow here? The fact that it is a parallel fan-out?
The RegionBanchOpInterface is limited in its ability to track the actual data-flow here but that's another issue.
