 Replying to [comment:1 swissspidy]:
 > Previously, there was the same issue with responses, see [37989]. We
 should be consistent with return types, so I'd consider this a bug.

 This is indeed likely to break some more plugins, given that typehints
 fail and `is_array` now returns false, but I also embrace changes such as
 the introduction of Requests and headers now being case-insensitive is a
 nice feature. Hence the suggestion to keep the current implementation and
 updating the docs (although that may not fit with WordPress's
 compatibility policy, I wouldn't know)
