The current expl3 bundle doesn't actually complain if one does

\let\eTeXversion\undefined

before loading expl3. So the test is still valid until that changes:

\documentclass{article}
\let\eTeXversion\undefined % Or use plain TeX, of course
\usepackage{expl3}
\begin{document}
\csname engine_if_etex:F\endcsname {NO ETEX!!!}
\end{document}
