As someone with no clue:

a) what's the advantage of having a native widget style, compared to using 
QtCurve settings? Are there things missing / not implementable in QtCurve?
b) do you share the git history, i.e. did you do a proper fork, or did you 
reimport the sources and started from scratch (I hope not).
