everything in userspace == high security. programs, software won't clash like they do on *nix, windows due to isolation. same benefits of snaps | flatpaks. but now you've a microkernel which is 1. fast 2. easy to patch 3. stable ABI something Linux doesn't have.
In what way does software "clash" on *nix? The isolation provided by snaps and flatpaks is 99% about isolating devs from having to worry about deps and different platforms.
Which are complete and total garbage insofar as actual isolation. If you think you can run malware in a snap and not be pwned you are kidding yourself.
