Version 1.3.0 brings Controlling compatibility. It currently is available for 1.21.x and 1.20.1. The other versions are coming in the following days.
Modrinth: https://modrinth.com/mod/keybindspurger
CurseForge: https://www.curseforge.com/minecraft/mc-mods/keybindspurger
Note: As always, Curseforge is weird and the Fabric version of 1.3.0 for 1.21.x is still not approved while the 3 others got approved under 10 minutes
