@hisacro - well, the longer term future is never all that clear, but in the more short to mid term, there are ports being worked on for the Furilabs FLX1, and the Brax Phone 3, that should be promising options for those that want to support companies that target their products specifically to be privacy respecting.
After that, the Fairphone 6 has been announced and will very likely get a UT port as well. Volla, despite being a small niche operation, has shown some resilience and consistency, with UT support being enabled for every device they have released, so I think we will see more from them in the future as well.
Pixel 5, 6, 7, and 8 (and variants of these) should be doable for Halium based ports, it just takes someone that owns one of these devices, that has the needed patience and technical know how, to volunteer for this effort.
Regarding Xiaomi phones in the future (which includes brands such as Redmi and Poco), those were already kind of a pain the a to get their bootloaders unlocked, and with Xiaomi's new HyperOS (their new bloated skin on top of Android), they have made it even harder to unlock. I had to use a third party hack called "Hypersploit" in order to unlock a Poco X3 NFC which came with HyperOS 1, and apparently this hack no longer works on Hyper OS 2.
