Yeah, like that one time when Twitter and Facebook banned spreading of a mostly true article about Hunter Biden. Oh, wait, that rejects your point, man. Social networks are much more venomous.
But it does not work that well. Some individuals(not many) do apply to higher standard while the others just slack on the trend wave. And they can do more harm because their responsibility is almost everywhere.
RSpec is written and read mostly by developers. Unlike those tools that business likes to use and abuse developers with extension requests just to feel more control over the situation.
My point was about the tools that let people do the job they'd ask to do programmers otherwise, but it is also a nice touch. Although, I think it is not only about JSX, virtually any modern framework markup part is not easily readable by non-developer. With complexity of the clients and trends we have now it is not fixable and won't be for a long time.
