The corresponding macro in tab-like environments is called
\tabularnewline.  Try:

--8<---------------cut here---------------start------------->8---
\documentclass{article}
\begin{document}
\begin{tabular}{ccc}
  ab & cd & ef \\
  gh & ij & kl \tabularnewline
  mn & op & qr
\end{tabular}
\end{document}
--8<---------------cut here---------------end--------------->8---

I think we should treat \tabularnewline like \\ and \newline and
\linebreak like \par.  Does it make sense?

You mean check the current environment every time during filling?
