Since when? The part of policy you quoted says the copyright file should be in
debian/copyright, not must.
Sorry, but I don't know the exact history of the policy. The actual

"Non-conformance with guidelines denoted by should (or recommended) will
generally be considered a bug"
So we can discuss about the severity of the bug, but it still remains a
bug.
