Surely you’d never get it out of your hair…?

It keeps owner and group permissions numerically - there’s no promise that those will match up when un-tarring to another system.
There aren’t even standards between distros on system accounts - daemon on my Rocky Linux box is id 2 and it’s 1 on Debian based things. Games is id 5 in Debian - and that’s the sync account on Red Hat…

On the other hand, if you need to transfer that data to another machine, rsync works to keep track of uid/name pairs and as long as all users are on both systems, the transfer will end with appropriate permissions and uid/gid intact.
