Ho-hum, so I gave this yay-thing a try, as a binary, out of CachyOS repos, and let it run an outstanding update of 77 packages, mostly new Plasma/KDE to 6.5.4 from 6.5.3. It even discovered some things which I must have installed manually via makepkg from the AUR, mainly i7z(probably during discovery, when the system(s) were 'new' to me), some microsoft fonts, and even Hexchat, which I've forgotten about, because I switched to KVirc when Hexchat began to crash. It doesn't do that anymore, at least not during autoconnect to EFNET & Libera Chat. Didn't test further. Did reboot with the usual insane brazenness of kill -9ing Firefox from within htop beforehand, to have it reliably restart my session, with all its windows and tabs in there. Yay -Scc, erasing all btrfs-snapshots, and so on.

Closing all other apps, terms, filemanagers. Klicking restart. Hands off. Very quiet and fast boot. Sddm appears. Login. Plasma is there. FF reloads as it should. Everything else works. Still ultra-smooth.

So Yay!?

(Squeekily screaming: *Oh my gawd!1!! Nao my (almost) pristine binary system iz tainted!1!!*)

You were saying?

Edit: Hrrm. When Hexchat began to crash... So I've told shit about no app ever crashing. But that was a general problem on Distros which updated the underlying substrate faster than others, IIRC.

It was just 'bitrotten'.

Very annoying at the time because I've been used to it since a long time, and had it heavily customized and themed, but (binary!) KVirc came to the rescue, so I've forgotten about that. Sorry.
