At this point, web design 'ecosystems' are essentially money whirlpools. They're complex, so they require programmers skilled in using them, who in turn make more sites which need more programmers, and so on, and the network effect takes over and cements this feedback loop in the structure of the jobs market.

And the frameworks are churned continuously and are also bug-ridden nightmares, so that continuous development and support is needed to keep websites functioning and secure.

Any reduction in framework complexity threatens the whole edifice.
