I think there is sum truth but as alwys it does not go for all situations and moments in this life.
woman might prefer more femine looking man when they are pregnant,when they are looking for long time relations and so on.
Dominance,masculinity has always been more important in finding and fighting for partner,impressing females...
Ofc it does not automatically mean that we bearded guys cant take care of family!
I find it to be evolutional development too,strong sex charectistics do not play THAT important role anymore but i have to agree that media and stuff has negative effect on this too.Creating wrong image and stuff.
