[e2e] Why do we need congestion control?

After some additional thinking: "Fair dropping" is exactly what we 
attempt to do in the moment.

However, VJCC and flavours affect the /throughput///while the 
decongestion work affekts the /goodput/.

So both solutions will encounter the same difficulties, however one of 
them is cheaper.

O.k., workshop paper, that's fine. That's the purpose of workshops: 
Gather ideas, present them, assess them.
