Now that we're past rc2, I'm inclined to close this as `Won't Merge` — this reads as adding new fp16 conversion support rather than fixing a bug/regression, which is what we're limiting backports to at this stage. If you think this should still go in, can you provide justification (why it's needed now vs. next release) and an assessment of the risk/blast radius?
