Merge conflict is unfortunate, the encpipe package in all-packages.nix right above engage doesn't exist in 23.05, so the diff isn't clean 😅

[CobaltCause]

I just opened a manual backport in draft mode because it doesn't build with 23.05's current rustc version.

Edit: and I just closed it because we don't backport rustc.
