While this is incredible and I can't wait to use this with HTMX, I really wish it didn't require a CLI to generate the *_templ.go files.
Code generation is something I saw in Flutter/Dart a lot and it entirely killed my interest in it (mostly with JSON serialization/deserialization to classes).
Thankfully, it's by no means a show-stopper for me thanks to their hot reloading functionality. https://templ.guide/commands-and-tools/hot-reload
