1. Privacy of names in general

2. Treatment of people who have changed their names.

For #2 there is a specific rule dealing with deadnaming:

> If a living transgender or non-binary person was not notable under a former name (a deadname), it should not be included in any page (including lists, redirects, disambiguation pages, category names, templates, etc.), even in quotations, even if reliable sourcing exists. Treat the pre-notability name as a privacy interest separate from (and often greater than) the person's current name.

2. If calling black Muslims by their birth names were currently used as a way of signalling racism, then I suspect WP would adopt a policy for that as well.
