I don’t think that’s correct.  The .ins/.dtx files contain instructions
for generating files, including the .sty files, which are extracted from
the .dtx files.

Correct.  For some “packages” there’s really just a .sty source file.
But often enough .sty files are generated.

We have both kinds of packages in tex.scm.  Some where the .sty or .tex source
files are copied to the target location and some where the .sty or .tex files
are generated from the .ins/.dtx sources.

Whether a .sty or .tex file is a source file isn’t always obvious, but
sometimes they mention that they are generated from other files.

For some fonts the provided format *is* the source.

I haven’t found any such cases yet.  Could you show us cases where the
font license makes the font non-free?

Ah, thanks.
