Agreed, but because it’s a lot easier to just search for “React programmer” these days than it is to evaluate lots of JavaScript candidates, which has a much wider scope and proficiency level and make sure they’ll fit right in when hired.

But not because direct DOM manipulation is not inherently scalable. See puter[1] for instance, a fairly complex, 100k+ lines of code of jQuery.
