I agree, I took the hatch release off my previous 8P hatch and it was a pain but 'doable' if you are patient and half useful. - there is a lot in the hatch! it's just as much work to fit the new handle so you don't really gain anything by resorting to breaking it out!
I bought this rear view camera and it works a treat on my 2017 FL S3 saloon, it came fully adapted, I am sure they will do one for the Hatch.
Die Installation ist nicht einfach, minimale technische Kenntnisse werden empfohlen! Wir haften nicht für Schäden, die während der Installation verursacht werden. Leider zeigt die Erfahrung, dass 5 von 10 Car Service das Produkt nicht ordnungsgemäß installieren können.

This is for the car which does not need the ECU in the boot area, you will need to find out which type of camera you need, I bought the loom for the one with the ECU and didn't need it if you do give me a shout. (I am sure we can come to some arrangement)
I used this 'how too guide' and it was a great help.

Use them in conjunction with the workshop wiring diagrams and you will be fine.
My biggest struggle was removing the trim to route the cables through the car, for me it was awful the noises it made as it came out, but I got there in the end.
If I can be any help give me a shout, the scars are still fresh!
