Existe algum significado para a calvície do Capitão Picard?

Parece que a calvície de Patrick Stewart foi um ponto contra ele quando ele foi escalado como o Capitão Picard. De Memória alfa :

In the early pre-production stage of the series, TNG producer Robert H. Justman wanted Stewart for the role of Data. (Patrick Stewart: The Unauthorized Biography)
[...]
Stewart was invited to read for the part of Jean-Luc Picard after Robert Justman saw him during Shakespeare readings at a lecture at UCLA. Gene Roddenberry's first thought was that he "can't put a bald head man in the captain's chair". (TNG Season 1 DVD special feature "The Beginning")

Nesta entrevista em vídeo , Patrick Stewart é questionado sobre o assunto. Ele se lembra de um repórter fazendo a pergunta a Gene Roddenberry.

"Surely by the 24th century, they would have found a cure for male pattern baldness?" And Gene Roddenberry said "No, by the 24th century, no one will care".
