Why, yes, I have read the rest of it.  In fact, if you read further back
up the thread, you'll see that I quoted section 3.6 and discussed its
relationship to section 1.6, which you quoted below:

That's all well and good, but that's not where the trail of license
terms ends for determining the license terms of materials included in a
"Larger Work".  I'll quote 3.6 again for you:

  You may create a Larger Work by combining Covered Software with other
  code not governed by the terms of this License and distribute the
  Larger Work as a single product. In such a case, You must make sure the
  requirements of this License are fulfilled for the Covered Software.

Between these four sections -- 1.3, 1.6, 1.9, and 3.6 -- it is not 100%
clear what the intention (in a legal context) of the licensing as it
applies to a "Larger Work" must be.  Granted, it sure looks like no
other parts of a "Larger Work" that are not part of the same file as
code explicitly licensed CDDL would be covered by the CDDL, but a lawyer
could probably make a pretty good case for the license extending beyond
the explicitly licensed code in a case where a "Larger Work" is compiled
as a single binary executable.

In any case, even if the rest of the code in the compiled binary is not
in fact covered by the CDDL under any circumstances other than explicit
release under terms of the CDDL, one still has a source distribution
obligation for part of such a compiled binary according to the law and
the terms of the CDDL -- the part that is distributed under terms of the
CDDL, at minimum.  This means that a compiled binary that includes CDDL
code in its source files carries a source distribution legal obligation,
period.  We're chipping away at the "freeness" of the software either
way.

That's the obvious interpretation -- unless you've spent a lot of time
with lawyers.

See above, re the fact that even if the rest of the code isn't then
covered by the CDDL the binary is still subject to a source distribution
obligation according to the license terms.
