What If...? dropped concept included Man-Spider?

In a recent interview with 'What If...?' writer A.C. Bradley it has been revealed that a scrapped episode would have featured Spider-man turning into a real spider. The concept was apparently dismissed due to its body horror nature.

"A couple of episodes that were a little too dark. There was an original 'What If' run where Spider-Man turns into a real spider, and that was just too dark and too body horror for the PG-13 [rating]."

Personally, while I can understand why the concept was not done, we've seen Spider-man mutate into a Spider-like being in the past and in the comics we've also had characters like Spiders-Man (Below), it would have been nice to see them push the boundary of the PG-13 rating for some more horror inspired moments.
