How do I return values that have not been validated?

What is needed for: for progressive improvement and improvement of DX users.

When returning a value, you can insert the values that users entered back into place and it works fine if you return them from server actions

Possible ways

1. OnError
   On Error returns void, why can't I return what came from the client in the form of clientInput
   

2. Metadata
   It needs to be validated using the client and from which it is used for all server actions (And she doesn't have access to basically anything)

3. a function inside the utils of the schema method (handleValidationErrorsShape)
   He already gets an error, which is why there is no access to the initial information

4. Middleware
   It does not allow you to return the context or anything in case of a validation error

Conclusion: The schema method needs to be changed

I think it needs to be reworked.
Firstly, it is inconvenient to do each scheme in this way if you want to support progressive improvement (instead of onSubmit):

export const formDataCheckUpUserSchema = zfd.formData(formCheckUpUserSchema);

Secondly, with this method, which is now, it is impossible to return any values, even manually

You can try to change the logic of the schema. For example, when using a callback, take the previous one to the scheme, and for example the processing stage (that is, the argument will be the information received before the schema method)
because, for example, I don't see the point in expanding the scheme. This can be done without the schema method anyway, although maybe I don't understand something. Provided that this extension hopefully doesn't work every time a server action is called

why else is it convenient, for example, to make an information processing function instead of supplementing the scheme? You can use functions such as: zfd.processFormData (which is used inside zfd.formData) to parse form Data into an object and return it as parseInput.
zfd.processFormData will just allow you to pull the fields you need and send them as an object and allows you to use the normal schema instead of zfd.formData()

P.S. well, or give the user the opportunity to return something from onError
P.S2 Or ask zod developers to return incorrect values in case of an error, not validated values

The best way, I think, would be to allow a function like returnValidationErrors, only for serverError and for OnError and onSuccess
