That hasn't happened for me, but it has shifted from desktop to mobile for me, because, for me, desktop Linux is just about fucking perfect, and I see no need to change it. But, I do very much enjoy playing around with different things like lineage OS, and possibly post-market OS on phones.

I'd say my phone is my primary computing device so it's what I like to mess with and the laptop is just a system that I need to work whenever I pick it up and therefore it gets Linux installed on it and doesn't get many changes.

I would say my laptop is more like an appliance similar to my toaster. When I turn on my toaster, I expect it to work. And it's the same thing with my laptop for the little bit that I need it. And my phone is the device that I mess with, primarily.
