Unfortunately, no.

My interpretation of those sentences is that they say "use \SI and \si
with siunitx.sty v3." Actually, the following document typesets without
problems for me.

\documentclass{article}

\usepackage{physics}
\usepackage{units}
\usepackage{siunitx} % loads siunitx.sty v3, not v2

\begin{document}
\SI{30.1}{\kilogram} \si{\unit{\kilo\gram\metre\per\square\second}}
\end{document}

I'm talking about siunitx.el, not siunitx.sty ;-) Current siunitx.el
runs TeX-add-symbols for \qty and \unit unconditionally. That isn't nice
when the document loads physics.sty or units.sty (or both).

Sounds good :-)
