last time I checked, blind users could not even install any mainstream distro anymore, because they all switched to wayland, and that broke screen readers in the installer.

Waste of time, they don’t even fix the massive bugs the app still has for years :/

Care to explain?

In my experience… not really. I would say SDL makes the task of writing controller support code within your own applications easier and higher-level, but in reality it still has not much to do with “drivers” (I assume you mean kernel modules), which the kernel and OS stack already provide multiple unified interfaces for with things like jsdev/evdev/udev/hidapi, regardless of how you access those subsystems (via SDL or otherwise).

What OSes do not have any Rust code?

does echo 3 | sudo touch /proc/sys/vm/drop_caches change the available RAM at all when this happens?
