The difference is the creators probably planned Marco and Star even before giving anything to the public and wanted to take their time especially with them being the main characters while Pacifica seemed to was not meant to be a big character. While Pacifica got some appearances it focused on making sure she grew as a character over just having her just hook up with someone with only some mild implications towards Dipper in the long run including a hug, some bonding and ultimately signing a "See you next summer" card/note with every other friend of the twins.
