Perhaps. But if you have the resources (I’m running an n100 with 16g ram and it can handle a lot, thanks to Linux containers having very low overhead) then proxmox means you can easily add another function later. There are a few self-hosted services that suddenly stop seeming like too much hassle once you already have a virtualization platform with web UI. Maybe you decide you want a torrent client, or a home assistant installation, or next cloud etc etc
