Omega has no PDF mode, so AUCTeX does not allow similar use of PDF-mode
and  Omega-mode.  XeTeX is not yet supported in AUCTeX.  If we support
it, it will likely be similarly mode-locked.

Engines that do not even have a DVI/PDF choice can get along with a
fixed command.

Most definitely.  That's why it would be very good to have a working
lualatex command in TeXlive2008 if we can manage it.  Even if it
interprets utf-8 input via [utf8]{inputenc} for now, namely as a sick
combination of active 8-bit characters.
