I'm okay with overridable warnings, having to open system settings to override the verification, etc. It's a "huge safety win" for the 80% of users who don't really know what they're doing, security wise. But not for me.
I won't be using any OS that doesn't allow me to step outside its walled garden, if I have any alternatives at all. With macOS it's quite simple - the second they won't allow apps from unverified/unsigned developers, I'm switching to Linux. On mobile, I might as well switch to iOS, since I'm not really sure what else Android offers anymore that's so compelling, other than being able to install apps directly. And then I'll just wait for a Linux phone or something.
