Comment (by peterwilsoncc):

 > I get that (`fastcgi_finish_request` prevents setting further headers
 but) no non caching headers are sent afterwards by default.

 Sorry, I missed this question earlier today.

 The idea behind placing the headers inside the `fastcgi_finish_request`
 was to ensure that any full page caching plugins retained control of how
 to manage the wp-cron cache. Most of them do a check for `DOING_CRON ===
 true` and send out their own headers.

 To avoid repeating code multiple times, I think the change you have in
 your pull request is for the best. Caching plugins calling `header()` with
 expiry headers later in the process will replace the existing headers.
