react uses those same web standards. It will not stop working either. You may not be able to upgrade to the latest React version assuming there are breaking changes, but the same can be said for the various frameworks people use to create web components.
I might be nitpicking but, the transpiled version of React is the one that uses those standards. If you are thinking of trying to get a 5+ years old project working in a development environment you might effectively be out of luck.
To reduce the argument to a simpler one, this is effectively the difference between using vanilla js to build anything Vs using any abstraction over it that has a number of dependencies you don't control that are effectively a working solution of a dependency hell in a specific moment of time.
Yes, but then you are not comparing apples. Web components projects without a build step and relying on only stable standards are a subset of all web component projects. Same with React projects, though the ratios of without build vs. with build are obviously different.
if JSX is your issue, that means a web component framework like Stencil is just as bad as React. But then again you can use React with htm to avoid jsx if it really bothers you.
