drupal 4.8

This patch is laying dormant in the patch queue. What are the current sentiments? Is there convergence towards Gerhard's approach, or towards MimeMail/Send?

Has anyone enumerated the specific issues that remain?

I hate hacking core on my clients' installations but recently had to in order to meet the requirement that every sent mail gets logged (the watchdog messages don't qualify as logging in this case... needed more information delivered in a unified way). Since all mail is still handled by user_mail, I had to add a logging call to that function. Yuck! Where's the hook_mail?
