Current diff algorithm makes CW posts look like contributors have been abducted by aliens.
Line breaks may be all that matters for Klingons, but human beings are used to believe that character count, well, counts.
It is well known that rolled back changes are considered valuable contribution at Alpha Centauri, but we at Planet Earth tend to think otherwise.

A workaround to force Klingon diff display a major contributor as an author (tested here) is for the user to add then remove a dummy text with sufficient amount of line breaks:
