It's what should be called "a defective implementation of the DNG  
specification by Pentax". They're not the only ones who've produced  
defective implementations with respect to DNG files. It's not the  
specification that's at fault, nor Adobe: it is the software vendors  
who don't seem to understand how to be compliant with a protocol  
specification.

Since I refuse to use PPB/L as it is junk software anyway, the  
question is moot. I capture in PEF format and convert to DNG on the  
fly when importing to Lightroom. That renders the correct results for  
my workflow: compressed RAW files in the camera and properly  
formatted DNG files on the computer. There's nothing missing from the  
DNG files created this way, and what "private data" that Lightroom/ 
Camera Raw/Bridge might not use is not of any consequence to me.
