The FQDN mcr.microsoft.com is redundant because it's already covered by the existing *.microsoft.com wildcard pattern. The wildcard *.microsoft.com matches any subdomain of microsoft.com, including mcr.microsoft.com. You can remove mcr.microsoft.com from this list while keeping *.mcr.microsoft.com to allow subdomains of mcr.microsoft.com (e.g., <region>.mcr.microsoft.com).
