Yes.

But more important is, how can someone get the number of
pages?
* Currently I scan the pdf file for /Count entries and assume
  the maximum is the page number.
* This week I have learned about \pdflastximagepages. But is there
  a more elegant way than
    \begingroup
      \sbox0{\includegraphics{foo.pdf}}%
      \xdef\foopages{\the\pdflastximagepages}%
    \endgroup
    Result: foo.pdf has \foopages\ page(s).
    ...
    \includepdf[pages=1-\foopages]{foo.pdf}
