I want to come back to weight=0 for a moment, because it would allow use to make a node not receive any bandwidth until all its children are finished. 

For example, as I discussed here, a way to subvert the need for exclusive priorities is to work with a sort of priority "bucket" system with the placeholders. However, as can be seen in the 2nd image, P1, the buckets would get a weight of 1, where ideally that would be 0. 1 means they would still get 1/257th of the bandwidth (again, see P1, split between the HIGH placeholder and the HTML file). With weight 0, we could make this type of bucket system more semantically correct (arguably, 1/257th is too small to matter in practice, but still...). This might partially help circumvent the need for #2700, as discussed in
