remote forms: infering field metadata

Describe the problem

The new remote form functions allow us to beautifully centralize validation. The result is vastly simplified form components and templates.

With some information about the types of fields a form expected, we can almost programmatically generate forms based on the remote. We would need some field metadata, which at the least would include:

• Field names
• Field types (at least precise enough to guess the right <input type={...}>
• Whether the field is required or not (which is often rendered as a *)

However the current API doesn't provide us with any information on the form's validation schema in the remote.

Describe the proposed solution

The simplest solution is to provide access to the raw schema in RemoteForm. However, from what I can tell, the standard schema is pretty low-level and isn't designed to be consumed directly by developers.

A cleaner solution would be something like a remoteForm.fields getter which returns an array of field metadata that can be used to build a form.

Alternatives considered

• Manually building forms - already a much nicer experience than previously, but one wonders if parts of it can be automated.
• Manually importing the shared schemas to the frontend and parsing them, but this seems like a lot of work for this kind of this.
• The remoteForm.field method - although it seems to be built for a completely different purpose

Importance

nice to have

Additional Information

No response

No file or test is named in the issue. Start by locating the RemoteForm API and its validation schema handling, then compare the existing remoteForm.field method with the proposed fields metadata; done means an agreed API exposes field names, usable types, and required status for form generation.
