Do drones trigger the Vengeance Generators?

[contingencyplan]

Quick question: Do drones (in my case, from the Enclave Starship) cause Vengeance units to spawn?

From my limited experiments, this seems to be the case --- grab a bunch of drones, self-destruct, and immediately vengeance units spawn.

Is this intentional? Given that the drones are intended as weapons rather than ships and they will automatically die, could we exempt them from the Vengeance Generator spawn trigger?
