Hello -

I've adopted a number of zones and most of them contain "localhost in
a" records. I'm curious what current RFC standards state and
what the community considers best practice. RFC1537 states that zones
should contain a localhost record, but it seems that practice was
obsoleted by RFC1912. Is anyone aware of negative consequences with
leaving such records in place, perhaps a XSS vulnerability?

I'm itching to remove the records but thought I'd check to see if
there was a legacy use case.
