I'd also add a small meta argument: that it would be actively 
wrong to *allow* 'belated' acks to be added. In practice acks 
are most useful *before* a commit gets created and they often 
have a mostly buerocratic role afterwards.

So we should encourage timely acks (which actually help 
development), and accept ack-less patches as long as they are 
correct and create no problems. More utility, less buerocracy. 
Incorrect, ack-less patches causing problems will get all the 
flames they deserve.

Thanks,
