Having this phone for a few months and would very much like to use e/os on it.
Some (re)sources - like vendor - are still missing, anyway:
Hope that helps.
Is this any more doable now that there’s an unofficial LineageOS build?

You need to build it yourself. There are tutorials on this forum
It can be done when /e/OS-a16 sources are also LOS23.2 based
Some updated sources shared for the CN version of this device over at XDA (Github: vendor_xiaomi_dada, device_xiaomi_dada, android_hardware_xiaomi, device_xiaomi_sm8750-common) but based on this thread I take it we’re still out of luck unless someone eventually makes an A16/LOS 23 or (future) A17/LOS24 build.
/e/OS A16 is based on LOS 23.0. The team is working on A17 and would skip 23.x versions and directly move to A17 for all devices for which it is possible - official and community.
Other (maybe) useful repos here:
