My biggest worry with Immich is how to future-proof the albums. With photos sorted into folders, it should be no problem to access them in a couple of decades. With Immich, I have to rely on the software still working or finding some kind of tool to dump the database.
I remember that Immich has a mode to not use cryptic hashes but folders for storage. When I used it it was somehow deprecated due to some problems, but supported. I actually stopped using Immich because newer versions run the keep alive via socket.io with a Prostgres notify, which does constant empty WAL flushes, triggering empty page writes on idle.
Storage template is not deprecated
