There was some discussion related to this in bug#1779,
e.g. https://debbugs.gnu.org/cgi/bugreport.cgi?bug=1779#79:

  T-L mode is not suitable for Dired, because not every line is an
  "entry", i.e. the first two summary lines---which are also the reason
  why Dired does not use the header line.  Other Dired features, like
  showing multiple directories, also break T-L mode assumptions.
