I think the point of the message was not that pdftex should be fixing
included files, but that pdftex should not be doing something that the
pdf viewers then have to work around.

As far as I understand it, the poppler people are complaining that
copying accented text out of the pdf doesn't work right, because
instead of an "á" character, the file contains "a" and the accent as
separate glyphs, correctly positioned to look like if it was an "á",
which is fine for viewing, but not for text-extraction. I suspect that
this behaviour is too deeply embedded in tex to be easily fixable.
