I'm answering a comment chain about how Subgraph OS does not 'isolate' the network or USB stacks which is frequently brought up as an important deficiency in comparison to Qubes OS. My point is that this isn't a significant advantage of Qubes because such attacks are rare and difficult, and because they're even harder to perform against Subgraph OS.
I wasn't talking about AppVMs at all, but you can of course persistently backdoor Qubes AppVMs in numerous ways by writing to the user home directory. In Subgraph OS we design our application sandboxes to prevent exactly this.
