If you'll include that in the next release, you could use a customizable 
macro for displaying the nodes:

\def\pst at shownode#1{%
   \ifPst at showNode
     \psdot(#3)\uput[\ifx\psk at rot\@empty0\else\psk at rot\fi]{0}(#3){#3}
   \fi
}%

With this option, one can use the following to suppress showing all 
internal pst-optexp nodes:

\makeatletter
\g at addto@macro{\begin at OptexpObj}{\psset{showNode=false}}
\makeatother

But for pst-circ there is no easy possibility to suppress showing the 
internal nodes.
