[Feature]: Maintaining a mirrored form state for producing an isValid without displaying error messages.

[ZipBrandon]

What is the new or updated feature that you are suggesting?

In regards to #158, my implemented solution was to produce a 1:1 of the form with the form id of ${formId}_VALIDATOR. On all my inputs I have a useControlField/useUpdateControlledField to update the validator form when values change. I use the isValid of the Validator Form to enable/disable a Submit button when values are appropriate for the schema. Mostly this works without a hitch, but occasionally on more complex inputs it gets some weirdness. I believe it would be much easier and less complex if this optional ability was native to remix-validated-form. I don't know if this would be as simple as one-way syncing the form state to a duplicate. I'd be happy to work on a PR based upon any guidance.

Why should this feature be included?

This would enable a lot of different workflows succinctly and provide a great user-experience. Enabling submit buttons when schema is achieved ( my use-case ); displaying new form fields with valid schemas; Auto-submissions based on valid schemas.
