If you are making a web-app, if you decide to go Vanilla JS, you are eventually gonna end up with a react-like library regardless. Simply put, if you don't use it at first, you are gonna end up needing the same feature set. Creating DOM elements based on a model/state. Try making something as simple as a date-picker without one. Except if you decide to do it yourself, not only do you have to organise your business logic, but also the logic of how your custom front-end framework handles stuff. A front-end framework you'll have to train all your new hires to use. A front-end framework your existing developers can hold you hostage over. And finally a front-end framework that you will have to fix and support yourself, and that you can't google solutions to, and that has received zero scrutiny from a security standpoint.
