binder.forField(emailField)
.withValidator(new EmailValidator(
"This doesn't look like a valid email address"))
.withConfirmationMessage(
email -> email + " looks like a valid email address");
.bind(Person::getEmail, Person::setEmail);
The default handler shows confirmation messages in a status label, if set. It is not set as a "component error". IF there is a custom handler, then it can decide what to do with the message.

SHOULD HAVE, but not necessary for FW8.

Research direction
Start by locating Binder's validation flow and the default and custom validation message handlers. Implement confirmation-message support for field bindings, with the default handler using a status label and custom handlers deciding how to display it; done means the proposed Binder API and behavior work as described.
