They aren't gender neutral. A midwife is a woman who is with another woman when she is giving birth. A husband was originally the male head of household.
The words themselves are, they do not refer to the gender of the person. In practice, they definitely are. I think almost everyone hears gender in them (I do!). Proposing a new name would require a different argument to change them than Freshmen, or Firemen which are gender specific.
Like the word 'Captain' which simply means chief or leader. We do not change it now because there's no gender in it even though it was previously used only for men.
