What do you qualify as a "modern mainstream Android device"?

I think the median Android device out there in the world today — just by sheer volume of them produced — is probably a "Welcome" phone with a MediaTek 6580 chipset and a faked-capacity SD card; i.e. hardware that couldn't possibly run any Android version made in the last six years.

(Such phones could in theory run Android Go... but they often don't, because these devices are often running non-Google-Play-Store AOSP derivatives — and there's no un-Googled version of Android Go.)
