Feature Request: hasValidated as validation state

A common pattern is surfacing validation errors after the user touched a field.

It would be great if this state was stored on the validation object and flipped only when `validate` or `validateSync` is invoked and in the case of the async validation - once it's resolved.

Thoughts? I can work on this if there is buy-in.

Start by finding where the validation object is created and where validate and validateSync are implemented. The requested behavior is a hasValidated state that stays false until validation is invoked, and for async validation flips only after resolution. Done would require tests covering sync and async validation state, but the issue is very old and asks for maintainer buy-in.
