im not clear what makes that not a skill?

other people cant do anything with nextjs, or anything with any front end at all.

its applied knowledge, understanding how nextjs works, and using it to build some application

Libraries come and go, but understanding the web means mostly html, js (in the form of web APIs), and css.

I've also been using react professionally since 2015 and I've yet to see a nextjs application in the wild. It seems to mostly confined to the startup sphere.
