Comment (by tofandel):

 This was proposed 7 years ago and never merged, then closed two years ago
 because of the Rest API, it's indeed very sad it didn't make it 7 years
 ago..

 Should I do some archeology and dig up the fossile (aka reopen the
 ticket)?

 Because I still think the wp-ajax.php file should be included, the rest
 api is something that maybe overpowered for what wp-ajax.php would be used
 for (Eg: Simple actions. At the top of my mind: pushing a like button that
 makes an ajax request or getting a share count every 2 minutes, updating a
 single form field via ajax that need to be very fast) so basically every
 ajax request that is light and needs to be fast should pass there.

 And I'm pretty sure the rest API is ~30% slower than what this would
 achieve because of the rewrite endpoint (htaccess invisible redirect to
 index.php + preg_match iteration needed to find the requested endpoint
 then wp_query endpoint parsing)
