I use React all the time and don't currently work on a single SPA. Most of the time they are composable widgets that spit out hidden tags on a form. Even for simple things, React is usually much easier for me to reason about than the old jQuery way of transforming data and then transforming your DOM separately (or even worse, transforming your DOM, which is the same as your data). As a library, its comparable in size to jQuery, which is pretty much ubiquitous these days.
