Immediately formatted and switched to pop OS and I've never been happier.
For future reference, if you ever decide to switch back, breaking changes or ones which require manual intervention are usually announced on archlinux.org.

Have you tried OpenSuse Tumbleweed or Gecko Linux? Tumbleweed is a rolling distro but the maintainers apparently test all of the updates they push. OpenSuse can feel a but clunky (it asks for passwords for “everything” for instance), but theres Gecko, which acts a bit as a wrapper of a distro to make OpenSuse a bit more user friendly.
I've heard good things about tumbleweed and it even has support for WSL, so I might try that if I ever build a gaming pc and have to main windows.
I avoid it because I find it hard to use and hard-or-impossible to configure adequately. It takes a "my way or the highway" approach. If you like how it does things, it's great. If you don't, you're better off using a different DE, which is what I do.
I’ve tried adding desktop environments to a pop installation, but I really don’t like having all of the apps included with other desktop environments cluttering the taskbar menu and the like.
Also I wanted a distro without systemd and the init system is the one thing you can't choose or change on arch. I tried it but didn't like arch, in the end I moved my stuff to alpine which still runs my docker server.
In the end I chose FreeBSD which has a really nice combo of stable OS but rolling packages which is not common on Linux at all. And the community is much nicer IMO.
It's a user-friendly and maintained Arch with some goodies like kernel switcher and driver updater GUIs.
In regards to this specific incident, The Arch team did release a statement on how to handle the update.
