It's easy to follow, it's a knee jerk tribalism reaction and not a logical or informed one. Go attracts backend or anti-frontend people so anything intermingling the two will draw out the commenters who bemoan anything that realistically builds a modern website. Just ignore it, your choice for dev tooling is practical and makes sense to me.
It doesn't depend on node for runtime. Only for dev: the vite dev server, and js bundling, nothing else.
Also I've been a long time templ & html/template user, also used templui. gsx is born out of my ergonomics desire from templ. gsxui is similar to templui, but makes bundling possible. Also borrowed pipeline filters from html/template. But you're right, this does involve a _build_ step. But I think it's worth it.
Later I'll add the bundler free version. But really, vite has been so useful. Just treat it as another tool.
