Comment:

 The time has come, I think.

 Quotes from https://developer.mozilla.org/en-
 US/docs/Web/HTML/Element/a#browser_compatibility :
  Note: Setting target="_blank" on <a> elements implicitly provides the
 same rel behavior as setting rel="noopener" which does not set
 window.opener.

  [I]n newer browser versions setting target="_blank" implicitly provides
 the same protection as setting rel="noopener".

 All major browsers have shown this behavior for more than 2-3 years now,
 meaning that all browser that are still supported by WordPress support
 this (unless I have overlooked something).

 We should consider deprecating `wp_targeted_link_rel()` and related
 functions and stop adding it as a filter hook callback to a bunch of
 hooks.

 `noopener` in static `<a>` tags in wp-admin can be removed, too. I don't
 think it's worth the risk to remove it from post content though.
