HTMX, Unpoly and Twinspark are great, can't say anything about Raku.
I also really liked an idea about class-less CSS frameworks, as I was frustrated with all the `<table class="table">` and so on. Then I've tried it for one project where I had to integrate Leaflet map on a page. And it's just not possible to do with class-less CSS frameworks.
Since then I write `<table class="table">` and have zero problems with that.
