Either way, the lower dialects need to know what kind of broadcast anyway, so no materialization of the constant tensors should remain.

I think I am missing some context here. In a previous PR I saw this was based on some round-table discussion. For people who werent there in person can you please post some notes and provide some more context. Specifically, I want to get some more information about what you are refering to w.r.t `softmax` semantics...
