So this is another thing that needs to be fixed since it should allow for the calling app to decide what bit depth to use for output.  For Gutenprint we will definitely want 16 bit per channel output for example.

I think the PDF spec might have something to say about this, at least for vector I'm pretty sure it's supposed to be 16bpc float. But yeah ideally we'd clobber everything, including 8bpc images, in 16bpc channel AT LEAST. I know ACE does everything for Adobe applications with 32bpc float precision.

Yes.
