Seeing all three bars for each party member might not be required for everyone, but it is necessary for some people to do their jobs. If toggles are implemented to hide MP or TP bars, then they should be non-optional for jobs that have support abilities that affect MP or TP -- BRDs, MCHs, NINs, and ASTs should be forced to keep TP bars visible, and BRDs, MCHs, and ASTs should be forced to keep MP bars visible, so that people not fulfilling their support roles because "bars turned off, sry" isn't a thing.
