Ahh, I think I realize now where I went wrong: "the copyright file" is
Even if I recall and understand correctly that during the DEP5 process
leading to copyright file format 1.0 it was pointed out that the
debian/copyright is only about source, that is *not* the same as saying
that the /usr/share/doc/<package>/copyright files are only about source.
Source and effective licensing just happen to be identical in simple
cases. And copyright file format 1.0 just happen to only verbosely
cover source copyright (as I recall the addition of copyright field in
header section was only late in the process).
Apologies to previous posters who might have seen this all along and
tried to point it out to me. :-/
I'll setup a mechanism to have libav extend the copyright file for each
binary packages, adding to header section a reasoned effective license.
...and will start do similar for all the other packages that I am
involved in, as I examine copyrights and licensing for those and convert
to machine-readable format.
