Well if they came across a massive horde, or multiple Grimm on par with the Dragon, then they'd have use for a superweapon. They'd probably only develop such engines of annihilation/extermination as "just in case" contingencies, but then Salem would be quite eager to turn them agianst humanity.

Superweapons, with a few exceptions, require a sizable target or cluster of targets to warrant use, and even if the Grimm did presenst themselves in such concentrations, their losses would be covered eventually.
