Others have replied pointing out this is a strawman and that merit doesn’t make any sense as a metric if you have discrimination.
So remove discrimination. Put in the CoC that any information about gender, race, religion and so on must not be disclosed since it is not relevant to the quality of the code/work you submit. Then you have merit only.
I really find stupid that someone really think that his contribution must be accepted just because he is from a minority, irregardless the quality.
