;-) exactly.

I am mentioning steiner trees every year once since 20 year
in the hope someone will stand up and say he needs it in reality.
No luck yet.

Load splitting obviously is very important but was maybe not
a good example for using topologies given how BIER already has
a pretty good native ECMP scheme.
