If no hint was given that those cipher systems had been broken, it could be plausibly hoped that other nations would adopt similar systems after the surrender of Nazi Germany, considering them secure. Sure enough, the Soviet Union soon cobbled together a similar system, probably inspired by captured equipment. One can only imagine the frisson of glee that ran through the cryptanalysts when they discovered they could re-apply techniques and breaks they had already honed against the Germans.
So, on the whole, it made absolute sense.
