This should be 2 patches.

You aren't deprecating either. That means still documented and labeled 
with 'deprecated: true'. But again, just 'fixing' the vendor is not a 
reason to deprecate and for us to have to carry the old compatible. We 
deprecate when there is some advantage to it such as using common 
properties instead of vendor specific ones.
