For some reason they don't release userdebug versions which was a dealbreaker for me.. (the device should be secure, but not against me)

But if you wish to build it from source, it could probably be a good option.

I don't currently have any root on the phone, but I reserve the right to add it or run the userdebug build at a later date

		We could use it to install magisk, but that wouldn't make the build proper "userdebug" one. I fully agree with your original comment - AOSP security model is NOT a proper solution to the security problem, and I'd add to it that it was also designed to be anticompetitive - Google can do what third party apps can't. Android architecture is tainted by Google's business model and it shouldn't be used as an example of a secure operating system..
