Not a front end dev but this is why I love using vanilla js and pre rendered html in side projects. Easier to maintain long term as I don’t have to deal with ridiculous framework updates and feels snappier.
Sharing a vanilla codebase can be complicated, but I am finding that it is possible to convert others to this religion with a little bit of pair programming.
Once someone experiences this path, you may find they get hooked on it pretty quickly.
I never experience slow frontends. It's always either very slow requests, probably to some Java monstrosity, or newsletter/cookie modals, that makes me leave a website
