I love games as an introduction to programming. But then you have to teach kids how to do collisions (or physics), you have to teach them how to keep track of multiple sprites that behave the same but are in different places at the same time (I'm talking about classes, yes), and it's harder to point to a "real world" usage of game programming... which makes it harder to get your course approved.

I know, teaching today's web standards means they'll be out of date within the next ten years. But I believe the improvement of the web is asymptotic and will slowly come to a halt in the coming years... that and I would never forgive myself for not refreshing a course when it's too old to be applied to the real world, as a pragmatist. Finally, I don't think Vue will beat React too quickly.

(I'm not an educator, but I've spoken with a few on some of these topics.)
