Comment:

 Adding the performance tag for the perf team to review.

 The only back-compatibility issue I can see is if a developer is abusing a
 hook between the current `send_headers` location and the proposed
 relocation to `exit` early. I'm thinking something like this dreadful
 plugin to
 [https://gist.github.com/peterwilsoncc/de643a6f3ae3271cb2ab6c47f6e2fdf4
 forbid certain query string parameters].

 I do like this idea though, it will certainly help plugins determine if
 they need to send additional headers to avoid caching, indexing and the
 like.
