GTK 4.16.0 released, now defaults to Vulkan renderer on Wayland

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.

Huh but GPUs only support it since like 2016 or 2017. Older ones won't be able to render GTK4?
As per https://blog.gtk.org/2024/01/28/new-renderers-for-gtk/ and https://www.phoronix.com/news/GTK-4.16-Released :
You can still use either a new OpenGL renderer or the old OpenGL renderer. This can be set with the
GSK_RENDERER
environment variable (e.g.GSK_RENDERER=gl
)I would assume it will also probably detect unsupported hardware and switch to OpenGL automatically but I don't have any source to back this up.
I hope at least distros will make the switching automated because without it a lot of users will have issues, especially since Ubuntu and Fedora use GNOME by default.
There's still OpenGL backends, a newer one that shares the same backend as the Vulkan renderer and the old OpenGL renderer.
