Most people do use their system for purposes other than gaming, absolutely, but I doubt browsing the web and using office apps are much impaired by the changes gaming kernels bring. The biggest risk would be raising system requirements. One that I, admittedly, anecdotally, feel is increased USB polling rate making my mouse and keyboard feel more responsive. I can't find the article, but I seem to recall reading about Ubuntu adopting a kernel config change that POP_OS already used related to memory.
Pop! OS is an amazing distro, i am using it since 2021 and i never think about switching to anything else. I have cosmic installed on my oldest laptop (12 years old) and everything just works out of the box. Cosmic looks great, still alpha and missing some stuff but you see where it is going. It offers way more then vanilla gnome.
I truly hope Zorin would embrace cosmic and get their templates and stuff over there. The magic lamp for sample or wobbly window.
Alpha 6 came out today. I just tried it out. They've made solid progress.
