React isn't required for client-side validation or non-spec form inputs.
Doing form validation in event handlers for DOM events works very well, and a simple script tag or custom element is all that's needed to build a multi-value select.

I really don't want to go back to the jQuery days. You do you, but don't say it's easier - it really isn't.
BTW you can just use Preact if you're worried about the bundle size. I do that, it's perfect and just a little performance impact, usually not visible in small apps.
I reach for a state machine whenever possible to manage the complex flow of the multi-page or multi-step form, even if react is still used for custom inputs.
But it's not that necessary in my case, my forms are usually not complex statecharts, just a lot of individual and largely decoupled complex form controls - multiselects with rules, map pins, tag inputs with autosuggest, data grids etc.
