Well, the specific thing that we've bumped into in this case is that 
support for immediate is greatly slowing down HA queues. We could be 
smarter about this, at the cost of tangling the code further. So if we 
want to make HA queues faster (and we do!) we can either keep immediate 
and add a bunch of code at the same time, or remove immediate and delete 
a bunch of code.

There are quite a number of places where we have notably greater 
complexity just to support this weird feature that (we suspect) no-one 
uses. It just feels very disproportionate.
