I like an I use scoop alongside winget after many years of Chocolatey, but there are many packages not available through scoop, mostly because there isn't a viable portable way to install them. Also, scoop does nothing to take advantage of the MSIX Containers that sandbox apps, so that they can be cleanly update and later removed.

I'm considering automating the conversion of my most used apps to MSIX, so they can get always installed in a clean way. That may break certain apps like Steam, which need to install outside the virtual FS, but I hear MSIX supports global registry an global FS access exceptions nowadays, so not all hope is lost.
