they have long ignored the Google dependency

What a silly thing to say.

I'm absolutely certain that no contributors, and extraordinarily few users, are ignoring the risks implied by the google dependency.

A pixel with Graphene is the best option for a daily driver for as long as it's viable. I expect that's everyone's understanding of the project.

I don't really see how this project can "pivot to a non-android platform", as I imagine none of their codebase can be transferred.

Sooner or later the project will become non-viable and we will all switch to whatever the best option is at that time.
