I just don’t agree with this from any perspective.

First, the impact is minimal. React or a similar framework is not that big. In fact, React + ReactDOM is roughly the same code size as jQuery - 100k vs 85k minified.

Second, your custom DOM manipulation code is probably going to be a bit less optimised than a widely used library.

Third, you are overstating the difficulty. I would expect any competent front-end engineer to be able to pick up whichever of these frameworks is required. The different skills are a matter of a little on boarding and studying. Of course, there are many unskilled JS developers out there, but I don’t think that’s an excuse.
