Just to chime in here. To be clear, I think dropping a vdom implementation into a page is a good middle ground between full blown “framework” and “roll your own js”. I’m not familiar with vue, but I’ve used React (a library!) to great effect on pages that require that extra bump of behavior.

It’s such a shame that many of these tools are pushed as large SPA solutions when they can just as easily be included ad-hoc over a CDN when necessary.

* And I agree that it’s just madness to wire up your own components once the use case becomes anything more than the most trivial behaviors.
