it didn't quite come across as a suggestion, but if it was only a 
suggestion then ok; it's not really a practical option.

I know how it works for new drivers; they need to be good enough to 
maintain forward and form a burden on the stack/maintainers. Any 
remaining items need to be small enough to not be a 'risk' for users.

No. Arjan looked at driver and sees a rather clean driver compared to 
some of the other recently merged drivers, sees a list of relatively 
simple todos (some of which obviously aren't merge stoppers, others 
are) and hopes that this driver will be treated objectively without 
the appearance of having different levels of bars depending on what 
your email address ends with.
