You see more features as better, I see them as unnecessary bloat. HTMX targets users that want easy and minimalist ajax.
Once you get past the simple landing page or hello world app all those things you call “bloat” come in super handy. Otherwise you end up with a custom undocumented untested unproven probably insecure rushed out implementation of what the “bloated” solution gives you. Same applies for Unpoly vs htmx. Unless you’re building just a hello world landing page, as I said.
