It’s kind of interesting to me that this statement:
The main point I’m driving at is that you have to write your CSS in a fundamentally different way, using a pseudo-language that changes per framework.
Is the same reason why people are opposed to writing jss/jsx et cetera, but here it is used as an argument to the detriment of other frameworks.
I feel it’s pretty safe to say that the tools are all useful, and should be evaluated for what they do well, and used accordingly.
I really want us to stop pigeon-holing front-end architecture to one eco-system. The tools can work in harmony to produce the best results.
