That's not relevant. When engraved is used, we automatically include xcolor.

May you elaborate?

I guess that you are referring to

    When using listings, you also need to make use of LaTeX package
    "listings".  The "color" LaTeX package is also needed if you
    would like color too.  These can simply be added to
    org-latex-packages-alist, using customize or something like:
    
      (require 'ox-latex)
      (add-to-list 'org-latex-packages-alist '("" "listings"))
      (add-to-list 'org-latex-packages-alist '("" "color"))

We can indeed include color package, but I do not see why we should do
it by default. We may instead include it conditionally, only when
listings backend is selected by the user.
Just as it is done for engraved.
