Issue 387 (std::complex over-encapsulated) seems to be what you are
referring to and the final remark is...

    "The LWG believes that C99 compatibility would be enough
justification
    for this change even without other considerations. All existing
    implementations already have the layout proposed here."

...but I don't know the time-scale for things like this being adopted,
even if (for the sake of argument) everyone thinks its a good idea.
