Should 0x7f be treated as a control character?

RFC 8259 mandates Unicode, but then [implicitly contradicts Unicode](https://tools.ietf.org/html/rfc8259#section-7) by excluding [0x7f (DEL)](https://www.compart.com/en/unicode/U+007F) from the control characters. Doesn't that make DEL an ambiguous case?
