Any appararent drawback of using the following approach...

\definetextbackground
   [test]
   [ location=paragraph,
     leftoffset=1em,
     before={\blank[1cm]},
     after={\blank[1cm]}]

\startuseMPgraphic{mpos:par:columnset}
   path p;
   for i = 1 upto nofmultipars  :
     p := multipars[1]  topenlarged 1cm bottomenlarged 1cm;
     fill p withcolor 0.9white ;
     draw p withcolor \MPvar{linecolor}
     withpen pencircle scaled \MPvar{linewidth};
   endfor;
\stopuseMPgraphic

\starttext

\input knuth \endgraf
\hairline \par
\starttextbackground[test]
\dorecurse{13}{\input knuth \endgraf}
\stoptextbackground
\hairline \par
\input knuth \endgraf

\stoptext
