I do not see any downside changing our recommendation from using color
to using xcolor in the docstrings.

My stance is to minimize the number of loaded packages to the bare
minimum. If something is not strictly necessary, we do not load it.
Loading a bunch of extra LaTeX packages increases export time.

In the future, when we have the new LaTeX preview branch [1] merged, we
will cut the number of loaded LaTeX packages even more, only loading the
packages that are necessary to export the specific document
contents. For example, if the exported Org file does not contain images,
no image-related packages will be used during Latex export.
