Looks like it’s behind an experimental flag, only applies to new rooms, and isn’t available on the public app.element.io instance right now (the Labs screenshot they showed doesn’t show the option on element.io+matrix.org when I checked just now):

For it to work, looks like it needs another in-progress feature to allow new members to decrypt previous messages (Matrix can’t do that yet???):
https://github.com/matrix-org/matrix-spec-proposals/pull/4268
(That one isn’t even in the spec yet, it’ll take a lonnnnnng time before we see any real movement on it, possibly a year or two. A year or two before you can see encrypted messages from before you joined a room. Insanity.)
A contributor calls this encrypted metadata feature a “partial prototype:”
https://github.com/element-hq/element-meta/issues/1214#issuecomment-3714132569
And that issue was opened in 2017. Pretty crazy they’ve been discussing this for nearly 10 years and it’s just now “a partial prototype,” but that’s Matrix for you.
Bazzite is amazing, nearly bulletproof even?
I had a few times where it booted to the grub emergency shell, but it literally just fixed itself. Just reboot and it uses the other A/B slot. And the next update attempt just fixes whatever the problem was. That’s only happened twice in the last 5 months since I switched. Most longtime Linux users should be very familiar with the grub emergency shell, but I’ve never been on a distro where it just fixes itself. I don’t ever have to think or worry about updates, it’s just a reliable daily driver. It’s sick.
As people have said, Bazzite is immutable. You can install system packages/libraries if you absolutely need to, but you really should run your custom stuff in a Distrobox instead. Distrobox is preinstalled, supports graphical apps automatically, and most of the time you won’t even notice it’s not your real OS.
I think Bazzite is more stable and usable than Windows now. I’m tempted to switch my parents to it, it’s been much more fault tolerant than Windows 11.
