Snaps on Android, Windows and iOS

Hi guys.

Silly question: is possible to install/run a snap on an android smartphone, windows OS or on the iOS?

I know there have been initiatives that could have allowed a greater compatibility of snapd with them like this one to support the android devices fastboot or the Windows Subsystem for Linux (WSL)…
so I was wondering if will be ever possible to install my favorite snaps on other OSes, what are the missing pieces and what eventually is not possible to do and that therefore absolutely prevents from having snaps on them

Snapd (snap daemon) needs the Linux kernel to run, so it might be possible to be coded to Android. However with Windows it would only be possible with wsl, and with ios it’s impossible
