Why not?  This particular example is produced from @dfn in Texinfo,
which should emphasize its argument.  In the printed version
"packages" is typeset in slanted typeface (and without the quotes).

> There is no additional emphasis on quotations in books.

But we are not talking about books, are we?  We are talking about Info
manuals, which are mostly documentation of software.
