So Bucky implies in CW that the other soldiers can be kept under relative control, presumably through similar trigger words to his own, mind wipes, or drugs. But Natasha only ever heard rumors of one Winter Soldier, and it doesn't seem like they've been used in ages.
All that effort, training, and expense just to ice the soldiers indefinitely after one show of disobedience? Let's say that HYDRA got them under control enough for some missions.
The real reason they've been shelved? Their team tried to initiate a trash party after a mission. The other soldiers, used to being treated as elite HYDRA assassins, were having none of that and started gutting and dismembering their handlers. Maybe they castrated some people. Maybe Karpov. Basically just a total and horrifying bloodbath.
Bonus points if the Winter Soldier's watching this like "Oh hey, maybe my new siblings are kinda cool after all."
HYDRA/Winter Soldiers "The doctor, could he control them?" "Enough."
