I was playing with COSMIC on Fedora since mid-May, or around 3 months before the first alpha. It’s been pretty solid for me though there are still bugs and missing features. I see why they’d want it for F42, but I’m just not sure if System76 can have Epoch 1 released in time for that. They still have Alpha 5 by the end of December, Alpha 6 planned for the end of January, and maybe 2 or 3 betas before release. So We could only have Epoch 1 (first full release) End of March (or even later), which I’d say would leave too little time for extensive testing to meet Fedora’s standards. Just because I’ve barely had issues on my fairly standard setup doesn’t mean that others haven’t been plagued by issues. So my take on it is I want it to happen, but I’m not sure if it can happen for F42, so maybe the contingency plan to delay to F43 might be a better idea, but ultimately only time will tell.
