Looks promising. However my recommendation is create single components for common elements you use a lot...
Like... have a structure like resources/js/form/elements
where you might have:
Input.vue
Email.vue
Password.vue
and all types...
set some sensible defaults put use props so they're all overrideable.
Then create forms by model:
resources/js/users/forms:
FirstName.vue would look something like:
<template><form-input extraJson:"{readonly: true}" /></template>
Then your users/form.vue would be like"
<template>
<first-name />
<last-name>
<email>
</template>
Then say you have two types of users like users and customers... and two different forms -- you can reuse the email/name input modules in other forms so you don't duplicate content. I use inertiajs+laravel+vue though, and handle validations via laravel and don't generally need to use the whole json schema thing, as it just makes for more code. I like handling the validations in the backend and let the frontend just focus on ui/ux.
Json schema also has many tools for validation, which is nice if you're passing the form data around.
