You have a good point about things coming together, but open source often is a lot of design and development by committee, or interest.

Librephone appears to be taking existing linux approaches, and specifically reverse engineering the SoC blobs to be completely free. I may have mis read, but it doesn't appear they are building another android distro for android phones, as they already have done that in the past.

Just tried to learn the difference between these and it seems like:

- Graphene - For current devices only - An alternative for phones that are supported and updated by Google. Security Patches, etc.

- LineageOS - For devices while they're supported or may not be updated that often. Support can be sometime by community members.

- PostmarketOS - devices that no longer have a maintained Android version for it, can just become a linux computer. Mobile functionality doesn't necessarily.

Some phone chips overtime end up having a hardware security flaw that software can't fix.

I really enjoy using Android. Part of the issue is not all deices get timely security updates, even if they get monthly updates, the updates might be from 6 months ago. Google might release a security patch but sometimes it has to go through the device manufacturer, and maybe even the mobile company. Pixel / Android pure installs seem to improve this a bit, but it's hard to have complete trust.
