Because using a hold queue makes it more smtp agnostic rather than having to figure out way ever wacky way postfix or other smtp needs things to works - or in postfixes case whatever wacky way weitse wants postfix to work this week<br>

I have found that header_checks take place in the "cleanup" stage ( <a href="http://www.postfix.org/BUILTIN_FILTER_README.html#what">http://www.postfix.org/BUILTIN_FILTER_README.html#what</a> ) which is before several other stages ( <a href="http://www.postfix.org/OVERVIEW.html">http://www.postfix.org/OVERVIEW.html</a> ) but I have not yet found anything confirming that a Received header is added before the cleanup stage is reached.<br>
