This has nothing to do with compiler. You can add it to
`org-latex-packages-alist'.

See `org-latex-classes' docstring: it should be ("AUTO" "babel" t).

AFAIR, there is no clean way to handle that, so we let users decide what
they want.

See `org-latex-classes' docstring.

I didn't know that. I'll fix it in master.

I use neither xetex or luatex so I cannot comment of this.
However note that default packages should be very limited. It is easy
enough to add more of them to standard packages.
