I've something to share for running Snaps on Halium devices, and it's a gpu-2404 provider for Snaps to take advantage of.

The idea is to ship userspace drivers as snaps to consume by other snaps, and it's providing the same ABI-compatible equivalents to EGL, GLESv2, etc.
Fun fact: the gpu-2404 interface provides a way for hybris-2404 to set up the LD_PRELOAD hack that maybe a handful of devices rely on. It fits beautifully in there.
