Having spoken to Greg (who may or may not be chiming in), it appears that the authors of PDLT were only considering one kind of infinite width limit (as evidenced by your use of the word "the"). But Greg considers a general family of them. The NTK limit indeed has no feature learning, whereas Greg analyzes entire families, some that do have feature learning, in particular, one that has maximal feature learning. So there is no contradiction with respect to past works.
