Hello Arno,

LaTeX3 as a 'native' format will not be LaTeX2e + packages, but will be
rather different. It is possible to build a native format without any
LaTeX2e code loaded, but it's rather limited at present! Basically, with
some hacks you can at least typeset something, but it's not really usable.

On the other hand, it certainly is possible to build the LaTeX2e kernel
with expl3, etc., built in. The question is 'why?'. At this stage, I
don't see much gain over simply loading the package-mode material.
