You probably don’t have much on that system and/or you have a lot of discipline…
I did reinstall it after max 1 1/2 years (Arch btw.), either because of breakage, or weird behavior, or it was a chaotic dumpster fire.
At some point I discovered NixOS and was sold (and am still sold after 3 1/2 years using it). But it has a steep learning curve, though it certainly got better over that time.
