I will have to keep a Windows install due to I'm a developer, and Windows is still more relevant for games (also GUIs for debuggers - is there any for GDB?), so no big deal.
You're the only developer, then you burn out on the project.
You underbake the UI so much your project becomes infamous for how hard it is to use, complete with an elitist userbase that just screams "git gud" memes at everyone asking for help (most often happens to dev tools).
The rare occasion, it'll become like Krita, modern Blender, Audacity, etc.
MacOS is way more often worse than Windows than how Linux does it.
Linux sometimes have important settings hidden in config files that are different in every distro. Sometimes an API is legit worse in Linux, than in Windows.
MacOS has a lot of things that cannot be set at all, constantly deprecated APIs, not to mention it's locked into overpriced hardware. CoreAudio was only better than the Windows native offerings until XAudio came, and Pipewire for Linux seems promising from at least a developer standpoint.
