The request nikic was making, on my behalf, was to pull this entirely outside of the `AI.getAllocatedType()` branch of the function, since I'm moving towards being able to delete that branch, as he mentioned. That said, I don't think that change is actually necessary for this PR. As long as you're confident in your tests here representing a cross-section of what this optimization should be able to do, then I think it will provide good coverage to ensure any future changes preserve the intent here.
