ROMs rarely work as one-size-fits-all-devices, yeah?

I only know of four smartphone categories of phones that are really available in the markets around the world today, en masse.

1. The big tentpole phones available from Samsung, Google, Moto, and maybe two other players.

2. Boutique devices from vendors like Nothing and Fairphone with limited reach to global markets (like, being Euro only, or being only distributed in markets that can buy into they ideology, etc). Nearly all of them prices or is MOST humans' reach.

3. Chinaphones. A mix of fly-by-night brands with ghost shifts in factories that make many varieties of phones with other people's designs, but have extremely limited first party support and probably zero ROM support from the global community ... And then the handful of tech markings like Xiami, HTC, Huawei, and anyone else that bends the knee to the CCP. Virtually no NA market penetration in this decade, and tremendous barrier for entry, for most of the Western world. Also, security issues galore.

4. iPhones.

All that to say, I don't think a more featured OS existed it's the way forward, with people all jockeying to make new ROM's for everyone to NOT be able to run on their phones.

I'm hopeful folks smarter than I will be able to come in about the potential for sandboxes in it phones with their own capacity for running unsigned apps, like a virtualization platform.
