I suspect you may want to use something like the `LaTeX-label'
function, or ultimately call

    (funcall LaTeX-label-function arg

if using `LaTeX-label' is not possible, but I still don't know exactly
what you want to do.

I don't think you'll be able to start a flame war.  I do love RefTeX
as much as you, but you should keep in mind that they're two separate
packages and things are not going to change in the near feature,
unless AUCTeX replaces the default TeX mode in Emacs and this looks
fairly unlikely for a number of reasons.

AUCTeX and RefTeX have a good interface, to the point that you, as a
developer, usually don't need to care of the other package as long as
you use the appropriate functions/variables.

Having a look to already written code is a good way to avoid wasting
time in reinventing the wheel.  This has been my workflow:
automatically inserting a new labels makes me think to "equation"
environment or sectioning command.  Let's have a look at how this task
is accomplished in AUCTeX:it uses `LaTeX-label'.
