As a former academic in tech I'm tickled that you think 'a deep dive' is normative while 'to delve' strikes your ear as strange.

No judgment! I'm delighted, however, that language is so supple ("leverages domain-local synergies")

Probably a generational thing?

OP cited youtube as 'delve'ers, which skews young, so I'm guessing it's that your cognitive 'ear' is tuned to the technosphere
