Comment:

 Reopening this because I believe there may be a way to accomplish this in
 a way  that doesn't duplicate a lot of code and cause security
 vulnerabilities and be backwards compatible, and add no new ajax hooks.

 I think we can make wp-ajax.php the primary ajax handler, at least from
 the standpoint that the actions are fired in this file, separate out the
 functionality in the switch statements in admin-ajax.php into actual
 functions, have admin-ajax.php hook into the wp_ajax_ and wp_ajax_nopriv_
 actions, and include wp-ajax.php

 This is just a thought, with a proof of concept patch.

 Let me know what your thoughts are, if it is deemed that this still isn't
 a good scenario then we can close the ticket.

 I still believe we can do without this patch as long as we keep pushing
 education as the answer.  One of the biggest points of confusion I see is
 surrounding the fact that admin-ajax.php lives in wp-admin, and people
 assume that it should not be used for frontend ajax.  We also see
 scenarios where the security put in place on wp-admin causes issues.  I
 offered a suggestion in a previous comment for this as well.

 This patch should be backwards compatible, and would allow both admin-
 ajax.php and wp-ajax.php to be used as ajax endpoints.  It moves a lot of
 code that should have probably been in separated functions to begin with,
 and utilizes the WP API for hooking in, rather than huge switch
 statements.

 In any case, I figured I had some free time, an idea and thought we could
 give this another go.
