afaiu it is because the plating tends to build up faster in the easy to reach areas so you risk the via opening plating over before the walls, trapping stuff inside
I believe you can get vias plated all the way to solid copper but it takes a long time so I suspect expensive
It amazes me that they can plate any copper midway in a tube that is
10 times as long as its diameter.We do need to find out how thick they can plate the vias at some reasonable cost.
