Sanitization like Mongoosejs about vogels

On second review I think this is two different things.

1. Is to prevent data that was not a part of the schema from being saved.
2. Is to prevent certain data that is a part of the data being saved, like an admin flag

This is actually already supported. Here is an example schema definition which will strip unknown attributes before creating a record

var schema = Joi.object().keys({
    username: Joi.string().alphanum().min(3).max(30).required(),
    password: Joi.string().regex(/[a-zA-Z0-9]{3,30}/),
    access_token: [Joi.string(), Joi.number()],
    birthyear: Joi.number().integer().min(1900).max(2013),
    email: Joi.string().email()
}).options({ stripUnknown : true });
