I'd go for an API like Joi.boolean().truthy(...).falsy(...), the standard being the current Joi.boolean().strict() (true/false).

It doesn't look like it is supported currently based on the code for that to be converted (or for the Boolean to be configured to override the flags).

I'm sure your PR would be reviewed if you wanted to add a new set of values there, personally I'd love to see Boolean take some configuration like this:

var obj = Joi.object().keys({
  enabled: Joi.boolean({
    truthyStrings: ['yes', 'y', 'true'],
    falseyStrings: ['no', 'n', 'false']
  }).required();
});

My thoughts precisely. I think I'm going to make this a breaking change and accept configuration.
