JSONForms: Customizable JSON Schema-based forms 4 years ago
At crossref.org we are building out a form-based application using this library, and also working on the development of the VueJS/Vuetify renderer set https://github.com/eclipsesource/jsonforms-vuetify-renderers.
The UISchema is a compromise, and I think that largely is a result of the limitations of JSON Schema when applied to form generation - it's good, but it's not perfect.
There is an open discussion on the JSON Schema GH about creating a custom JSON Schema vocabulary for form generation, which could answer some of these limitations https://github.com/json-schema-org/community/discussions/70
