Thanks for this !
Just to better understand some of your technical choices : are you using microG ? Do your phones pass SafetyNet ? (there are many apps that do not work out-of-the-box with custom roms, e.g. bank/payment applications, etc). !
May I also ask : why did you create your own rom rather than contributing to existing projects with a similar target ? (e.g. /e/, calyxos, grapheneos, which start from LineageOS and add some extra work to mimic or sandbox Google Service Framework and precisely care about privacy...)
