Comment (by lkarsten):

 I think we either should leave it as it is, or invent some new
 BereqProtoUnset/BereqLineProtocol/BereqChange vsl class to log that it
 changed (or unset.)

 That was we get the same (or similar) behavior as BereqUnset, but without
 overloading BereqUnset to also include non-headers.
