To confuse matters even further, I interpret the above text as already
implying that the client MUST use the Content-Base header if present,
and would maintain that all clients which do not are not compliant
with the text of the spec.

However, I would not mind if Content-Base is deleted.
Content-Location can be used to do the same thing anyway.

Did you ever test if clients do use the Content-Location header to
resolve relative URLs in the entity if this header is present?
