That would be awesome to see. OEM bootloaders (and their fuses) and dealing with the proprietary drivers/blobs are the things that really need to be tackled with resources to be on as many devices as possible. I doubt those companies will want to play nice depending on whatever Google demands to be allowed Google Play Services. It is so hard to actually break into the OS market for mobile at all, but it is dedication that LineageOS has had that has kept it alive and updating. I hope that all the custom ROMs and the Linux Mobile OSes help each other out to the benefit of everyone on all levels of phone/tablet tiers.
