You probably mean WSA, Windows Subsystem for Android, only available on Windows 11… for another month. At which point support for it will be dropped[0]. It's a bit sad 'cause I, myself, do use it for a few things. Also, by default it required installing the Amazon Appstore, which I don't think is available for download anymore. So the only way to use it now would be to use the script from the MagiskOnWSA[1] which downloads it somehow, and at the same time, installs Magisk. If that even works.

It looks like it fell apart because none of the existing app stores wanted to support it (Amazon originally did, then pulled out), and Microsoft, in a rare moment of clarity, realized that nobody likes the Microsoft Store.

Actually, Wayside would have been a nice name for the software that became Waydroid.
