"if someone changed their name and ask for not being called their former name ever again"
Writing someone was called XYZ, is not calling the person by that name again. It is just stating a historic fact.
Not all historic facts are relevant. Using someone’s old name when relevance can be achieved by stating the person was transgender is preferable.
