The code didn't use QProcess as in the early days of main_wayland.cpp Xwayland had to be started before the QGuiApplication was constructed. As this requirement doesn't exist any more we can use QProcess and improve the interaction by e.g. provide useful error messages if Xwayland couldn't be started.
