Be able to benchmark with a control flow similar that the one used for branching, collecting intermediary information (also very useful for debugging);
Train agents that can be uncertain and prefer SCIP policy.

Proposed implementation
Default branching is performed by passing None as an action / branching variable to env.step.
Alternatively, I though one could give a token, like
env.step(ecole.environment.default_action)
The advantage would be to avoid involuntary default branching (if users unknowingly get a None output in their policy).
The motivation is two folds:
