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.

Why are they not using the protocol-level solution, is the pipewire way just simpler to implement? Also, why is the screen sharing fix just an extension and not part of the core protocol?
Dunno. wlr-export-dmabuf-unstable-v1 exists for a while. And wlr-screencopy-unstable-v1. Last one implemented in Sway and Mir.
Kde uses kde-zkde-screencast-unstable-v1 which requires pipewire for some reason and Gnome seems to use unregistered extension.
GNOME and KDE both support the desktop-agnostic xdg-desktop-portals which provide general desktop APIs and that's what most DEs are now converging. The portals including screensharing, input emulation and much more. The problem is that sway/wlroots doesn't want to support it as they're somehow vehemently against a D-bus dependency
