Advice sought for 6.9 and Arrow/Category

I want to use ghc-6.9 for improved support of type families, but I see that the change to the Arrow interface breaks some of my libraries (since (>>>) is no longer a method of Arrow).  Will this change really be in ghc-6.9?  Does anyone have coping strategies for keeping libraries working in 6.8 *and* 6.9, particularly ones that define instances of Arrow?

Thanks,  - Conal
