I am an ardent anti-custom-ROM/OS advocate

Not because I inherently "trust" Google/Apple/etc ... but because I do not have the time to worry about random incompatibilities with my devices - I've got kids, a full-time job, and other stuff to think/worry about ... fiddlefutzing with a phone (or other device) OS is about the LAST thing I want to take up space in my schedule :)

GrapheneOS, despite its human problems (as admitted by its project lead), does have at least near perfect if not perfect compatibility with the Google Pixel devices listed as release targets on the GrapheneOS website.
