It's no noise, because PDF 1.2 knows the /Next entry in
action dictionaries for other actions.

Small example with dirty trick because of lacking support in pdfTeX:

\immediate\pdfobj{<</S/Launch/F(/usr/bin/xterm)>>}
\edef\LaunchObj{\the\pdflastobj}
\pdfcatalog{}
   openaction
   goto page 2{/Fit]/Next \LaunchObj\space 0 R/Dummy[}

First page
\vfill\break
Second page
\bye
