[pstricks] Why can't \psarc, \psellipticarc, and \pscurve have ArrowInside?

Dear folks,

I noticed that \psline and \psbezier are the only open curves that can have a middle arrow via ArrowInside.
Thus, the remaining open curves (\psarc, \psellipticarc, and \pscurve) cannot have a middle arrow.

Here it is the minimal working example for you.

\documentclass[pstricks,border=12pt]{standalone}
\usepackage{pstricks-add}
\psset{ArrowInside=->,linecolor=blue,linewidth=2pt}
\begin{document}
\begin{pspicture}[showgrid](6,-8)
\psline(1,0)(5,0)
\psarc(3,-1){1}{180}{360}
\psellipticarc[dimen=money](3,-3)(2,1){180}{360}
\pscurve(1,-5)(2,-6)(3,-5)(4,-6)(5,-5)
\psbezier(1,-7)(1,-8)(5,-8)(5,-7)
\end{pspicture}
\end{document}

Could you update the package such that all open curves can have a middle arrow? It is not only useful but also to maintain consistency.


Thank you in advance.

Best regards,
