But couldn’t someone get into a situation where they want to use GObject and
Cairo reference counted types in the same port?

If this is the goal, there are multiple ways to achieve it. There are template
techniques to do it that we decided not to use before, because the tools don’t
support them well enough. There are macro techniques to do it that we could use
right now and then we could have these new classes share code with RefPtr,
RetainPtr, and JSRetainPtr as well.
Making one class that is one of these three based on a compile-time setting
does not seem like the right way to go to me.
