Auctex exporter is not yet part of polymode exporters. It's trivial to add but
it wasn't high priority because of the already in-place pdflatex and latexmk
exporters that should fit most (all?) needs.

Too late;) Polymode is very likely to be the default from next ESS release.

Why exactly is that?

That's more of a question for rmarkdown developers. If possible you can side
step it by putting pandoc that comes with your emacs distribution in the shell
path. But I don't think you should bother with that at all. It might be better
if users of Rmarkdown or polymode would install pandoc separately.
As for polymode and rmarkdown/pandoc integration, it is already there by default
(since a month or so). "M-n e/E" inside .Rmd files should be providing the
option to set the exproter to Rmarkdown, Rmarkdown-ESS or pandoc.
A bunch of polymode UI improvements are in working. Most notably there will be a
separate option for how to display some files (i.e. you might want to display
PDF and HTML files outside emacs). With this addition and Auctex integration I
don't see what else polymode weaving/exporting would lack as compared to current
non-generic ess-noweb framework.
