For me the introduction of a new set of rules is a deal breaker. I'm -1 on the RFC the way it is, and +1 if we implement these 'hints' as implicit casts, plus change implicit casts to emit E_CAST in case of loss of data or 'bogus' conversions.
Just to be clear, implementing E_CAST would require introducing a set of rules for when to throw it. By a strict reading of your message, that's a deal breaker.
In other words, you can't make an omelette without breaking eggs. We can choose not to make the omelette, or we can choose which eggs to break.
