What’s fine for text isn’t good for applications, and doing UI design using text formatting tools like floats and clear was never going to be simple and intuitive. By contrast, newer layout modes like Flex-box and Grid are maybe a bit more complex off the bat, but once you grasp the mental model are quite intuitive with far fewer sharp edges.
So I think in fact the solution is what the CSS committee has been doing, standardizing new and more intuitive layout modes optimized for the specific types of layouts being poorly served by what currently exists.
tl;Dr No.
