I agree with you on that one. However, I think it's unexpected that
files from the texmf-modules/doc directory are included by default.
Hasn't it been made more strict some time ago? Why does this still
work (or better: fail):

  %% \setupexternalfigures[location=default]
  \starttext
    \externalfigure[test]
  \stoptext
