I would argue requiring your whole team to learn a new framework-specific templating language and patterns is not simple, compared to using something that is plain JS/TS which the whole team already knows. It also complicates hiring, as programmers who know JS/TS and can pick up React/Angular/etc are a dime a dozen, in contrast to trying to hire programmers to work with a niche framework which has a lot of domain specific knowledge.
