I've been using HA since near the very beginning, and I recommend using the Proxmox Helper Scripts script that installs the HAOS VM. That's what I do. I disagree with the OP, HAOS simplifies a lot of stuff like addon installations, updates, backups, and migrations. It's the main supported way to run Home Assistant now and the one they spend the most time testing. HA is probably the most critical piece of software I run, so I want it to work, and I don't care about also running other stuff on the same system (other than addon's) because I can do that in a separate VM. Having spent years running it bare metal and in docker that certainly works fine, but HAOS made it a lot less effort to manage and has been very reliable when I ran it on a standalone machine and then when I moved it under Proxmox.
