I’ve always treated my home server with public facing services as presumptively compromised. I don’t put any data on there I wouldn’t want to see become public, and any data I actually care about losing is backed up to the cloud with an append-only key. The NixOS config lives in a git repo not on the server. If something bad happens, I can wipe the machine clean, redeploy the image, restore my backups, and we’re back to the status quo.

So, my threat model hasn’t changed much!
