Comment:
It is indeed recommended in https://github.com/swaywm/sway/wiki/Running-Sway-without-systemd
I wouldn't add it to the `wayland` package, but to each compositor individually, because `libwayland` only requires `XDG_RUNTIME_DIR` to be set (socket path must be in a standard location agreed by client and server in order to establish the connection).
