I think the point is that without the [0pt], the following line's [0,1]
gets interpreted as a length parameter for the line break, \\.

: Eric S Fraga, with org release_9.6.6-418-g294a4d in Emacs 30.0.50Earlier version gives me this:
\begin{center}
\begin{tabular}{ll}
(a,b) & open interval\\\empty
[0,1] & closed interval\\\empty
\end{tabular}
\end{center}
\end{document}

I have several export filters that break because of this [0pt]. For example, I use <mid> in a table row (created by an R source code) to mark wherever I want a midrule using this:

(defun org-export-midrule-filter-latex (row backend info)
  (replace-regexp-in-string "\\(<mid>\\([[:blank:]]+\\&\\)+\\)[[:blank:]]\\\\\\\\" "\\\\midrule" row))

Now my \midrule becomes \midrule[0pt].
