Comment (by westonruter):

 In [changeset:"61111" 61111]:
 {{{
 #!CommitTicketReference repository="" revision="61111"
 General: Rename `wp_send_late_headers` action to
 `wp_finalized_template_enhancement_output_buffer`.

 Also update docs for `wp_finalized_template_enhancement_output_buffer`
 action and `wp_template_enhancement_output_buffer` filter to warn against
 attempting to open an output buffer in callbacks or else a PHP fatal error
 will occur.

 Developed in https://github.com/WordPress/wordpress-develop/pull/10443

 Follow-up to [61088], [60936].

 Props westonruter, dmsnell.
 See #43258.
 Fixes #64126.
