I'd like to disagree there. If the framework gives me a high level option
to append a *whole* pdf document (which the Append function provides), I'm
expecting that it's doing just that, including the embedded file. On the
contraty, if I iterate over all pages and add each page sequentially, I
wouldn't expect the embedded files to be added as well (does this work?).
Even if we agree that the Append() function should only append the pages of
the given pdf file, there's still the effect that previously existing
embedded files are still hidden in the pdf, but cannot be accessed
(evaluated by looking at file sizes). That's inconsistent if we agreed that
the function only appends pages.
So I think, either something has to be done to make the embedded files
accessible again (where I would need help for) or the embedded files should
be ignored at all when using the Append() function, so the result pdf size
won't increase by the size of the previously existing embedded files.
