While this may be true I would think you would have to also agree that it is also more humane (if that's the correct word) than dumping them just before pref. Neither is a wonderful option, more the lesser of two evils theory.
It's a "stigma" now, to not have a full or almost full invite list after the first round. Once that's no longer the norm I think we will find that fewer women drop out because they have fewer invites.
Of course that also begs for the standard GC party line about keeping an open mind and really looking at each chapter individually.
