I disable the login password by connecting my user automatically on my
LUKS setup. It is a few clicks away in most DEs I would guess.

Did you consider this instead of implementing what you propose?



Yes I did. I did the same on my machine. I only type passpharse and initrd have luks-key script, and gdm has autologin. But another notebook with LUKS setup has multiple users, so autologin will not work. This is not about autologin. This is about unlocking your machine LUKS with only login/password without having an additional passphrase to remember.
