A harpsichord ihas a very thin board and no plate. The structure is light and has trouble staying tuned as it is even with no bearing. I admit to knowing little about harpsichords except that they have little tension and a light sound. As to the question of why a piano soundboard needs adequate crown and downbearing the simple answer is because we know they sound better both in the quality of tone and in its ability to produce volumne/power. I'll let others cover the theory as they're better at it than I.
