Could mean almost anything but what generativist linguistics (or whatever the latest label for the Chomskyan school) does, which continues to promote the notion that language is essentially algebraic, that "grammaticality" is binary, and so forth. It's simply not the case that Chomsky is "okay" with approaches to the study of language which are not in accord wiht his own. He repeatedly dismisses whole subdisciplines as "uninteresting," but in context those complaints don't mean "uninteresting to me," they mean "worthless."
