Legal names aren’t 1:1 with author names. If they were, who’d verify that?
Validating someone’s association with an institution by name seems like a reasonable thing to do. Perhaps it wasn’t done in the past, but times and circumstances have changed. Trust in authorship is lower than ever, and for good reason.
Even if it's not a legal name, are you going to review the CV of an applicant who used a different name on every publication they claim authorship of? It's going to be pretty obvious someone is being nefarious
