At least it appears to be something that gets triggered. In theory, if a node is not under attack or heavy usage, this isn't a consideration. Doesn't seem to be a perfect solution as it still slows the traffic of legitimate users in the event of an attack. I don't know the full details, but in the worse case it makes it easier to semi-DoS, maybe not by fully making a node unresponsive, but by making the service so painfully slow that users may give up on it.

Only for those users who do not have proof of work capability, they get put at the back of the line, but anybody with proof of work capability, which was released last August, will do the work and be put higher priority. I know some people who run seed nodes for Haveno-reto and they had major DDOS issues until they got PoW enabled. It was taking like 5 or 10 minutes to get connected to the network. And now it takes about 30 seconds.
