You can save a copy of the page in a box and print the collection of all boxes at the end of the document.

\newcount\sectionpage

\installpagehandler{sectionpage}%
  {\global\advance\sectionpage\plusone
   \global\expandafter\newbox\csname sectionpage:\number\sectionpage\endcsname
   \dowithnextbox
     {\global\expandafter\setbox\csname sectionpage:\number\sectionpage\endcsname\copy\nextbox
      \actualshipout{\flushnextbox}}
     \normalhbox}

\starttext

\setuppaper[method=sectionpage]

\input knuth

\page

\input tufte

\page

\scale[factor=300]{\box\csname sectionpage:1\endcsname}

\stoptext
