Baking up as a good thing. You don't need to go to extremes either. Think about the actual surface area that is holding the crack together. The thickness of the bakelite, and the length of the crack. How thick is the 'superglue' on a tight crack? Pretty thin.
Putting at least something on the rear side can help you avoid another hairline crack, when the cabinet heats and flexes.
Sort of like finishing drywall seams without the use of tape. The tape helps hold the two sheets together when the wall flexes. (I say flex, but in very small amounts)
Backing the bakelite up, even 1/4" on each side, can help add additional strength to the crack, making the repair move as one piece.
