But personally I don't believe in drop-testing of concertina bellows because the heavy weight of the dropping end is creating a not-inconsiderable vacuum inside the concertina that's potentially harmful to delicate glued structures of thin leather, felt, fabric, and cardboard.

I would have thought (but don't know) that the pressure from letting one hang would be far less than the pressure & vacuum created during playing, even if you had a button pressed during playing.
