Can't tell email is optional using USERNAME_AND_OPTIONAL_EMAIL

[jwaltz]

It would be great if there was some way to tell that email is optional while using:

Accounts.ui.config({
    passwordSignupFields: 'USERNAME_AND_OPTIONAL_EMAIL'
});

Previously, I was adding a placeholder value to the email input field but this modification would be lost each time I updated the package.

Is this change possible or is there a better workaround you could advise me of?

Thanks
