I'm not sure to understand you, but, if you mean embed JPEG could be used
to workflow I have some doubts...
Generally, I think embed JPEG are not mainly in full resolution nor
compressed with a fine quality set. If not why the RAW+JPG shooting mode
After, I think it's easily possible to extract embed JPG from RAW file
with command line tool like Exiftool or Exiv2 (it's what Digikam use to
show preview I think). And more you can use software like Nautilus-actions
tool to automatise this for a whole repertory or a selection of files, but
I don't see here the advantage to shoot in RAW in this case. ;)
