Of course, what oaep-bearer could _not_ "define to not exist"
(no matter how much anyone (group) might desire this), is those
transformations, and their complexity, that are permitted on HTTP
that headerfield, e.g. through "middle-boxes", such as client-side
HTTP proxies or server-side reverse-proxies between the original
creator and the final consumer, as well as permitted side-effects
of other application components sharing the same client (like a browser).
