I find it a bit weird that one of the easiest series of phones to get custom ROMs on lack official e/OS support for the newest models. Pixel 5 is not new enough to be covered by the improved Google update policy. LineageOS has support for 7, 7a, 7 Pro, 8, 8 Pro and Fold - even the tablet.
I know that we are trying to move away from anything Google and proprietary, but I have problems finding good, high-end models with e/OS support. My Fairphone 5 is OK, but I miss a good camera and a good microphone. Pixel phones are extremely popular, and support for them would give e/OS a broader appeal.
Others models you quote (that cannot be supported by /e OS “T” version) will probably be supported as soon as /e/OS “U” version will be released…
I have had or tested Pixel 4a5g and Pixel 5,6 and 7. I have fallen back to the 4a5g because it has better features than the 6 or 7 and the 5 is a bit small for my liking.
The 6 and 7 lack rear fingerprint reader and have similar camera’s as the 6-7. The reason my 7 sits on the shelf is the fingerprint reader is on the phone screen (like the 6). I’d stick to the 4a5g or 5 all day compared to the 6 or 7.
