Okay, did a check:
Effects.gd - date_bonus / date_bonus_t (Harmless but the description may confuse people)
TutorialNode - skills (still suggests that Submission / Loyalty can lead to infinite work)
SlaveList - Obedience colouring (harmless but may cause confusing colour changes if submission gets really high through some means)
SlavePanel - Still involved in obedience decay calculations (Harmless)
PositionSelectMenu: Submission still used for checking combat refusal (Harmless)
Dating: Fear description still mentions Submission + CalculateResults text
CharacterClass: Escape chance (harmless but could theoretically prevent Escape if it got high enough somehow)
Localization / En / Main: Several descriptions
