It's certainly not a thing to be resolved in the abstract, but it's also far from thing to be ignored as irrelevant in the abstract.
But I have a hard time imagining that my general point of "if there's headroom for a full 64-bit adder in the AGU, adding such is very cheap and can provide a couple percent boost in applicable programs" is far from true. Though the register file port requirement might make that less trivial as I'd like it to be.
