Dual booting is common for people playing games. While steamplay/proton works well enough for some games a lot need either a lot of hacking or a full blown windows to run. You can do GPU passthrough VMs if you have two GPUs but I have a miniITX board and no iGPU so that is not an option for me. Personally when dual-booting I don't share anything at all between the OS'es, but my understanding is that most do.
