What makes you think so?
(The problem is that your encoder now reports "I support transparency" and this will lead to funny effects depending in the colour space of your input file.)

Please also implement my other suggestion to make documentation and implementation match (and to match existing and new colour spaces, there is already an endianness-depending pix_fmt).
