I guess this means I'm going to Porsche maintenance hell, right?

Not necessarily, haha
The point is to not mix different types/brands of coolant, because mixed coolant tends to gel and cause all kinds of problems. I realized over the summer going back through my service receipts, that a mechanic I visited when I first got my 986 topped it up with non-OEM coolant (I didn't know any better at the time). Cue several years of mysterious coolant related minor issues, even after flushing the system. Of course, I am just speculating.
That said, if you are going from Porsche green to Porsche pink, there may not be that kind of reaction. Perhaps someone more knowledgeable about green and pink coolant can chime in, but I doubt Porsche would make the switch and recommend green be replaced by pink if it would case any issues.
