From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

No the implementations are per-compositor. The fact that this worked on X is due to.XOrg being a huge blob that every window manager relied on.
Look for the command in Mutter (GNOME), Kwin (KDE), or whatever DE you use.
That, is terrible
Its how Linux works lol. I mean there are tons of things per compositor.
The protocols are way cleaner and less, so it is easier for Distros to just write their own.
But for sure it is annoying that everyone wants to do their own. But that is not a Wayland problem, just nobody wanted to mess with XOrg.
Seems wasteful that each would need to build their own monitor power management interface.
They dont need to, a Desktop could just use another compositor and the rest of the stuff but they often dont.
wlroots
is a project doing some general work, but most of the others dont.Looks like it is hyprctl dispatch dpms on/off <hdmi_monitor_name> && hyprctl dispatch dpms on/off <main_monitor_name> Wlroots doesn't cover dpms
Also maybe via swayidle but I think dpms off, also triggers session lock
