This whole concept died because of styling and that era of everyone having their pixel perfect psd turned into a html table or a flash applet and you couldn't reconcile both, but sometime out there you can still find an old IntraWeb business app and you realize they had the components, events and everything figured out long before it became cool again.

I always wish for some RAD tool to show up for modern web stack again, but I guess it moves too fast to be worth it, and nowadays front and backend are properly separated disciplines.

Especially nowadays where AI changes how you interact with ugly languages like php, but benefit from their deep ecosystems, speed and super fast "build" times.

In fact, despite me being unable to look at php syntax much without vomiting, and finding languages without proper static types nauseating..I'm just more productive in those than in spa slop land.

The web and browser technologies has also moved a lot. The "client side rendering so users don't see a refresh and have an app like experience" is basically a 2010 thing.
