On Linux, often times you will be using SDL3 regardless, as sdl2-compat and sdl12-compat are the default implementations of SDL2 and 1.2 on some distros. This has a lot of benefits, from more apps working natively on Wayland (which gives lower latency than XWayland) to better controller support. Not sure what this meant for osu but I wouldn't be surprised if it made the actual switch less impactful for some users.
I was, however, somewhat surprised to learn Ubuntu 24.04 didn't even ship SDL3 to begin with. Turns out SDL3 is newer than I remember. This is likely part of the explanation why SDL3 adoption is lower than expected.
