We have to Export many thousand PSDs. As a Composite-Layer more than doubles the file volume (400 MB for single product image of a shoe ...) we have generally turned off Max Compatibility in PSD. This however causes the Bridge Exporter to fail – and Bridge doesn't even output a proper error message ("unsupported file format").

Please allow PSD without Composite Layers in Exports from Bridge. I realize that Photoshop will have to open the files – but this still would be very helpful. Right now, we have to use Batch from Bridge to Export.

Short-term improvement that takes one minute: Please add a meaningful error message, when users want to run Exports from PSD without Composite Layer. It took me far too much time to understand why all our Exports from Bridge fail and even Adobe-Support wasn't aware of the underlying problem = could not help.
