So the voice actors, sound engineers, performance directors, motion capture crew, etc would have been fixing programming bugs if they weren't spending time on recording romance scenes?
Seems more likely they were just different teams, doing different jobs to me.
Either they would have done something more useful like making dialogues or new characters, maybe we would have even gotten an epilogue in the release version, or they would have been paid less so other teams had more time or manpower to fix buff or add more content.
