Android apps have already been long since restricted in what syscalls they are allowed to use. And they have always run in a per-app sandbox. That's going to help tremendously. And for things like ptrace they don't have to support it at all. As long as Android Studio knows how to launch GDB or whatever on a Fuschia-based device, they're good to go. It's not like any app is going to be relying on ptrace otherwise, particularly since of course the ability to attach to anything else already isn't allowed.
