How to root the FP5 and OTA update - at your own risk

Thats how it would make sense I guess and is working on the FP4 (most times)

Recently it did not work always for some and I think they could not find the reason, its discussed in this topic

The OTA updates are delta updates and don’t contain a full boot.img, you will have to merge the OTA update(s) with the previous factory images to get a usable boot.img.

Wondering if its the same for FP5 and would it mean using this does not really work?
