That sounds like a threat.

Which I don't really like because it is rather unflexible.  I'd prefer
a solution where it is not necessary to have a whole set of variables
for a new engine but where this could be handled by a list of
processors which could e.g. include information about executables and
command line switches used at various occasions in AUCTeX.  Processor,
viewer etc. could be chosen by looking at activated modes, values of
variables or document properties.  A few months ago I played a bit
with the idea and wrote this:

(defcustom TeX-processor-alist ()
  '((tex . "tex")
    (pdftex . "pdftex")
    (latex . "latex")
    (pdflatex . "pdflatex")
    (omega . "omega")
    (lambda . "lambda")
    (xetex . "xetex")
    (xelatex . "xelatex")))

(defun TeX-processor ()
  "Return the macro processor as a string."
  (assq (cond ((and plain-TeX-mode TeX-omega-mode)
               lambda)
              (plain-TeX-mode
               (if (or TeX-PDF-mode TeX-DVI-via-PDFTeX) pdftex tex))
              ((and LaTeX-mode TeX-Omega-mode)
               omega)
              (LaTeX-mode
               (if (or TeX-PDF-mode TeX-DVI-via-PDFTeX) pdflatex latex)))
        TeX-processor-alist))

(defun TeX-set-processor (processor)
  (setq TeX-processor processor)
  (cond ((memq processor '(xetex xelatex))
         (TeX-PDF-mode 1))
        ((memq processor '(lambda omega))
         (TeX-PDF-mode 0))))

(defcustom TeX-expand-list
[...]
    ("%(processor)" TeX-processor)

But I never really went further down this road and thought it through.
