In macro set_char_box (in feta-autometric.mf) there is this code:

  special "% MF2PT1: glyph_dimensions "
          & to_bp (-b) & " "
          & to_bp (-d) & " "
          & to_bp (w) & " "
          & to_bp (h);
  special "% MF2PT1: font_size " & decimal designsize;
  special "% MF2PT1: font_slant " & decimal font_slant_;

mf2pt1 parses this in the (temporary) MetaPost output while creating
the Type 1 font.

mf2pt1 doesn't need this.

Experiment with what?
