Only diversity of thought should be “celebrated”. Being a man or woman, contextual minority etc, does not by itself bring anything. You could have a very “diversive” group that think alike and agree. Getting more women in STEM etc wont solve anything. Whatever that blob is that needs solving.
A: We need more women(minority y, handicap x etc)!
X: Why?
A: [insert silence or irrelevant argument here]

A: I think I get your point...but only a person that uses accessibility features, or those that work with people using those features on a regularly basis can give insight into if the efforts to make WordPress more accessible are actually working. That is why we need more diverse experiences and not just thoughts.

Same with women and any other marginalized group for that matter. Experiences in and of themselves give us better insight into a more well rounded product and the needs of the end user. It may not solve a code problem but can improve UI/UX and force us into other ways of looking at problem solving.
