KDE's PowerDevil supports both and prefers XRandR where supported: https://cgit.kde.org/powerdevil.git/tree/daemon/backends/upower As you pointed out, the nice thing about the XRandR property is that it does not require root access, whereas the sysfs interface requires going through a KAuth/PolicyKit helper to get root (which PowerDevil sets up with a default policy of "yes" so that all users can use it without a PolicyKit password prompt). It is sad that most drivers did not bother implementing it.
