This is just a Linux VM just like th Crostini in ChromeOS, so I’d expect similar 40%+ performance loss compares to for example proot container through Termux running natively.
The only thing this could probably offer would be giving you better OS GUI Integration into Android, like Crostini on a ChromeOS device. But if that is needed you might as well just use an Android port or an Android equivalent of your Linux software anyway, it’s not like you’d ever want to run Matlab, GIMP or OpenFOAM on your Android phone with its tiny screen anyway LMAO
Good thing this is at least very easy to block per-app with a Xposed module.
Although it is quite concerning indeed that there isn’t an easy and explicit way for you to be notified when an app tried to do this on its own, it would be nice to have a tool that can automatically scan an app to see if it does that
