> If someone can learn to solve just DP problems by practicing in leetcode then DP is a useless metric or proxy of someone’s ability to reason mathematically.

I'm not a fan of DP but I don't follow this logic. Does practicing maths problems for an exam make the exam a useless metric of mathematical reasoning?

Depends on the exam but if the questions rarely vary much from the practice material then mathematical reasoning is definitely taking a back seat.
