I agree mostly, but do disagree a bit. The actual experience of jQuery may not be as transferrable, although learning solid JS principles, learning how to work on a team, how to take part in a code review and a lot of other skills are very transferrable. Additionally, if you are part of the work of upgrading the codebase, those skills I believe are very in demand: How to understand what another programmer wrote, how to refactor it meaningfully and efficiently, etc.
