Microsoft PowerToys has a pseudo-tiling wm for Windows. There are loads of new options on Linux so while few people from the total population are using them, I think they’re growing.
I’m sure you could get by without a terminal on modern desktop oriented distros. Windows has it’s own weirdness, like having to manually edit the registry. Just because there’s a GUI for that doesn’t make it a better user experience. A ton of issues are basically unfixable by users on Windows and Mac. I’m not decompiling their kernel to figure out why sleep is so flakey. Linux is much more reliable.
