How did you check? I see
* -Dxcsecurity=true (XCSECURITY) in Arch, Fedora, Alpine, Gentoo recipes
* libXdmcp (XDMCP) being used on Fedora and Gentoo 
* libei (XTEST) being used on Fedora and Gentoo
* libdecor (CSD) being used on Fedora

That's reasonable if not for the above bugs shrugged off under
"works for me" blanket aka "maintainer's discretion".

Do you mean HiDPI patches? Plasma and Hyprland implemented their own
scaling while the rest rely on buggy workarounds. I'll probably drop
the patches if I can't manage to rebase after upstream rootful HiDPI.
To reduce POLA violation this was postponed until 2024Q2 branches.

IIRC, one Arch-based distro included HiDPI patches and old version of
Hyprland used to bundle those via Nix flake.
