Clearly there is a need to address the entire business of
essentially required changes to the LaTeX2e kernel for using
XeTeX/LuaTeX, and that impacts on expl3 in the current 'l3in2e' form.

Well, I couldn't agree more! A few years back, when I was still a bit naive, I even secretely hoped that my work on luatexbase (and even more importantly luainputenc) would be merged in LaTeX2e kernel... But it seems I'm not high enough in the LaTeX hierarchy to make this kind of things happen ;-) I still hope one day these packages won't be necessary anymore though...

Thank you,
