Again, speaking as someone who once wrote compilers and supporting
tools, that is not so.
A link editor does not need to know about that data its moving. in the
case of a compile link load cycle the link edit does not need to know
about the machine code. As far as its concerned those are just "blobs"
or data that can be treated as blocks. its only the linkages that its
concerned with. That's the whole point!
I admit that your role with DT is to manipulate what's inside those
blobs, the image data, so the linkages are important to you in that they
are correctly maintained so as to lead you to the image data. I can
understand why you are touchy about this. But as I say, link editing is
an old and well established practice.

Let's make it clear: I'm not talking about editing the picture data in
the blobs. You obviously have an understanding of that data so as to be
able to manipulate the images as you do in DT.
But the issue isn't about complete or incomplete and it isn't about
every last RAW file in existence. its about non-image data and its
about links. Its about adequately defined information.
