I don't see you referring to current one in your post.
PK was actually considered to be too inconsistent to the point that they buffed it in season 3, and even then it was not close to being the weapon that had most complains that season - that was charged rifle (the one they had to hottfix early into the season). And still people cried more over R99 than PK in season 3. So yeah donno what game you have been playing.
PK was not even moved to carepacket due to Respawn thinking it was too powerful, they simply commented that they wanted to change the meta.
And when it comes to bringint it back : "This season we decided to keep the care package contents the same to allow for the meta to settle in with the addition of the 30-30, a weapon that has a somewhat similar charging mechanic," wrote Eric Canavese, Gameplay Designer at Respawn. "We know the peacekeeper is a fan favourite and is one of the first weapons we consider coming out of the care packages each season so keep an eye out in the future!" No comment on the mastiff returning to the Care Package in exchange was made here.
