The other side of the coin is that we are getting better tools. Vue 3 with the composition API is a lot easier to work with, reason about and maintain then the legacy API. However the real counter argument is that vanilla javascript apps are also easier to write these days. If you have only a small interface to something that you have to maintain but only infrequently, perhaps a vanilla app is better suited. Vue apps are better suited if you want/need to a) get things running quickly (e.g. a prototype) and/or b) have a team of developers which need to maintain a large codebase together.
