I like this familly of technologies. Having an SPA-type app that's mostly backend.
Recently i've redone my app website (https://alt-tab.app), and I implemented a minimal spa.js that has a similar approach. I find the end result blazing fast, simple to maintain / reason about, few moving pieces. I used Early Hints, compressed every single thing, inlined CSS, etc. I don't know how i could even make it faster.
I recommend this approach for websites that are not very complex. Of course if i made a browser-based music player with a super dynamic UI, that would have been a different story~
