i thought i have been paying attention but i hadnt heard of Calyx or Graphene until this thread and a few others like it. im not married to lineage but i liked their leaving out a lot of google code. is it possible to do an alternate micro install just of play store functionality like in Lineage in the Calyx firmware? why arent Graphene and Calyx mentioned in the images and firmwares part of the XDA pixel 4a thread?CalyxOS is available. It is very similar to GrapheneOS in that it doesn't include GApps and you can relock the bootloader. One big difference is you can choose to install MicoG during install.
I've been using it since I got my 4a a couple of weeks ago and it has been a better experience than Lineage OS on my One plus 5
