Variations in the light even from faint stars can help establish what the surface gravity and thus other parameters about a star are. Unless the star is categorised properly, the size of any detected planets can't be accurately known. An earth to super earth planet at a distance from a particular star for water might have life. A gas giant, or a planet too close or too far is unlikely to have life. Thus knowing about the star is the most important thing.
