Why isn't there a separate field for women's married names?

After reading through the discussion on this topic I am still sticking to my method until I find out why I don’t want to do it this way. I add the married to the suffix in ( ) that then lists the female as
Given, Surname/Maiden name, and (suffix/married name).
on my list of people, I have only one name for each person and no alternatives because the married name shows in parenthesis at the end of each female’s name. This helps me to know right away who the female “belongs” too, so my brain does not get too boggled.
I also add nicknames, both genders in " " beside formal given name so it is where I need to see it.
Call me crazy and maybe I’ll be sorry later but for now I see
Sarah “Sadie” Mansur (Chalifour)
one time on list with everything I need to know about her. It may mess up my research, but I have not seen this yet and I know instantly who she is.

I’d love feedback on why this is a bad idea.
