Out of interest, why is the Dupre edition of BWV542 of specific concern compared to, say, an urtext edition like Barenreiter?
The greatest value of the Dupre editions is the fingering and footing, which is most carefully worked out to a thoroughly orthodox system.
Using that edition saves a lot of time in rehearsal. Dupre's Bach editions are not nearly as suspect as his alterations to Mendelssohn where, for example, he has added ties between chords that are not in the original score.
The urtext editions have no guidance as to fingering or footing, which can limit their usefulness to some players. This is not an issue for those brilliant people who never need to work at the fingering!
