I mean the punchline is: if you heat something up enough then you can get electrons to wiggle. At some level of cell wall thickness, the cost/time/annoyance of triggering a rowhammer exceeds the value of the attack, and other methods become cheaper or more practical. Ultimately, nothing that an attacker has physical access to can be completely secured, we can only raise the cost in terms of time and money to attempt to breach the system. Even a system with tamper-destructive enclosures have seen attacks (it's just more expensive and difficult than other attacks). In short, the more annoying/expensive you can make it to attack your system, the smaller the set of attackers becomes.
