As a Linux main, I don’t think it’s hard, but it’s also still not as good as Windows in some ways I find important. Fractional scaling for instance. I had a different resolutions multimonitor setup, and I definitely had more issues than on Windows. Also, now with two same reso monitors, I still have to switch to Windows to RDP into my work Win machine, because on Linux it’s so blurry due to difference in scaling, it hurts my eyes. Of course, I’m most likely in minority of a minority, but it’s still a thing.
One of my family cats is currently at the end of her life due to kidney disease. It really sucks, glad they’re doing something about it. Now if only they could do the same for dogs.
