The upside of this is that people who regularly review patches
(note: review, not ack) are more likely to have their patches
reviewed promptly by other people. i.e. this often devolves to a "I
scratch your back, you scratch mine" kind of arrangement.

In turn, this encourages prompt code review because it makes it more
likely that code is going to be reviewed quickly by others because
the others remember who reviewed their last patch-bomb quickly.

And the maintainer quickly learns whose reviews can be trusted, too,
which then leads to less load on the maintainer as reviewed-by tags
grow in trust value....

Cheers,

Dave.
