Even not knowing very well how to choose it, the fact is that real life
routers have implemented queues with a limited size.
I think that no one believes that queues in routers are free to grow
without limit, and that packet drops only starts when RAM space is
So, queues do exist on actual routers, are limited in length, and
implemented by code that was not left by an alien space ship. People who
build the routers (like Juniper) know what they have put into their
boxes, I presume.
