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.
But now you are talking about competence really. Just because you are colorblind does not mean you know how to make good websites for colorblind ppl. There are lots of variations on that.

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.
Not really, experiences by themselves adds nothing. Also the idea that a person because they belong to group X share experience or views with others that also belongs to group X is for me a really weird idea. Being a white cis male that doesnt mean you share experiences etc with other white cis males. You are arguing that your "group identity" so to speak defines you.
