Can you point out an example where this is ambiguous regarding encoding?

In HTTP content-encoding is never added/removed as part of normal
operations. Doing so creates a new resource variant, same as selecting a
different language or media type.

Agents naturally must remove content-encoding in their presentation
layer, and non-shared caches MAY to optimize reuse but if they do it's
their responsibility to properly handle the difference.
