I haven't really understood how it could be implemented.
But, granted, my pipeline design is relatively simplistic, and my
priority had usually been trying to make a "fast but cheap and simple"
pipeline, rather than a "clever" pipeline.
"Good, Fast, Cheap; choose any 2" Lee Higbe 1982.
Still beeter than "Good, Fast, Cheap: Chose one."
I was mostly trying to prioritize fast and cheap, but sadly it is neither as fast nor as cheap as I would want.
Though, ironically, will put at least some of the cost blame on RISC-V, which doesn't go quite so hard on the corner cutting.
But, one can maybe argue that it is a bit much to try to push for a 64- bit ISA that only natively has 32-bit integer multiply, ...
Though, this is not to say that other possible implementations couldn't try to do everything "properly".
