Android has something called GSIs (Generic System Images) that will run on any device that supports Android 9 and above. They don't always support custom hardware, but this isn't really any different from pure Linux. Instead of building a mobile ecosystem from scratch, why not build a community around submitting drivers to a build based on GSI?

AIUI, GSI's are not quite "generic", there are a few architectural variants. Plus they only give you a "system" partition, so the kernel and low-level userspace code (driver HAL, init-system etc.) are still Android-native and device-specific. Droidian is trying to implement something that's as-close-as-possible to Linux as GSI's, and it's not easy.
