And if you have a Debian machine that’s a couple years old and you want to upgrade it to the latest Debian version? Good luck.
To counter that with my anecdata, my Debian installations usually outlast the hardware they've been built on. I've found that it's much easier to start new builds with a backup (or the original disk) of the machine they're replacing, that's how easy it is to maintain a Debian system for me.
Heck, my first Linux desktop started out as Ubuntu Breezy, and ended its life as Debian Squeeze. Its replacement started out as Debian Wheezy, and is now on Bullseye.
I'm typing on a machine that's started life as Debian Etch, and has moved from a desktop, to a laptop and back, gotten cloned and is now three machines. It still doesn't use systemd.
