I assume it was intentional. Why would Andy talk about "scaling" otherwise?
And the worry was why the kdbus version killed the machine, but the
userspace version did not. That's a rather big difference, and not a
good one.
Possibly the kdbus version ends up not just allocating user space
memory (which we should handle gracefully), but kernel allocations too
(which absolutely have to be explicitly resource-managed).
