Comment (by johnjamesjacoby):

 > Are you meaning that the `$response['headers'][ $header ]` could have an
 array of header entries for a single header name?

 Correct! "could" being the operative word, unfortunately.

 It may be a string, but it could also be an array. It all depends on what
 gets sent back.

 > is this something on your list before 5.9 Beta 3?

 I see this strictly as a documentation change, without additional checks,
 errors, or auditing – at least for the here and now. As such, anytime
 during the 5.9 cycle where docs changes are allowed seems OK to me.
