You're stringing together a bunch of weasel words that are not a proof or a plausible suggestion of a proof.

"Suggests is more ambiguous" and "undermines the framing" are bare assertions you want to be true based entirely on your mental model that has several shaky unsupported axioms.

I would guess that anyone who describes that problem as "underspecified" has some kind of serious brain injury or is below A2 english proficiency and should be excluded from the dataset, but I would not assert that definitively as self-evident.
