I have disabled the db flag and reduced the mission priority to 0 so AI subs won't fire wakehomers anymore (unless they misclasify a target).
I left the depth unchanged so, as Amizaur said, you can still use it against subs if you reclassify it in the db.
A doctrine change to make it run shallow after enabling would be a good addition, unless you want to retain a bootlegged ASW capability, which is fine either way.
