Ethics - BAFTA new diversity requirements film awards

I went over the handbook section of ethics again this morning and I couldn't get the new BAFTA guidelines out of my head.

Here is the article I am talking about:
http://www.bafta.org/media-centre/press-releases/new-diversity-requirement-film-awards

In short, taken from the article:
From 2019, entries for Outstanding British Film and Outstanding Debut by a British Writer, Director or Producer will be accepted if they can demonstrate their film has addressed and improved inclusion and representation in at least two of these areas.
The areas of under-representation the Standards address are all the protected characteristics from the Equality Act 2010, as they pertain to the act. These are gender, gender identity, age, carers (including working parents), pregnancy/maternity, disability, race/ethnicity, religion or belief, sexual orientation and marriage/civil partnerships. The Standards also seek to address under-representation of people from lower socio-economic groups and ensure wide regional participation.

At first I was absolutely delighted with this announcement. It is a big step, as far as I know BAFTA has not taken diversity as a requirement for any of their entries.

After I went to BFI London Film Festival and saw a film together with an upcoming filmmaker we talked about how well the film was made but it raised many questions for us. I found it very odd that an indie film that was very realistic in many areas did only have white people in it. If you look at the ethnicity landscape of the city in which the story took place this is highly unlikely. It raised questions of the filmmakers choices, of her own experiences, the climate she grew up in and how she was 'taught' or conditioned how to tell stories. The film did address a foreigner living in the UK, she was white- European. As a European myself I loved seeing this character represented in an UK film, as most British films do not recognise all the European emigrants living and working in the UK and take that as a given, rather than making that the focus or 'problem' of the film.

So this film in which I, as a white, European, emigrant living in the U.K. I found myself being represented a bit in this one character. On the other hand, she had a completely different experience in the U.K in terms of diverse landscape as the people in my life are a lot from under-represented areas. And that aspect made the film leave a bitter taste. I mentioned the new requirements for BAFTA to my colleague and she said that the rules only were enforced for the upcoming season, and that this film could still qualify. I went over the article again and more questions came up: Why does this only apply to two categories? Why only two out of the four areas? (these are the areas: A: On-screen representation, themes & narratives
B: Project leadership & creative practitioners
C: Industry access & opportunities
D: Opportunities for diversity in audience development) 
It was a reminder for me as a filmmaker that awareness for all under-represented people is important. I am focusing myself a lot on sexism and racism in my film making journey but why not look at disability and gender identity?

It would be great to hear your thoughts on representation in art and on the new submission requirements for BAFTA.
