My use case is having entries in the blackboard with default values, which is already implemented in other frameworks like BehaviorTree.CPP.
The best option I can think of is added a new kwarg to Client.register_key() like so.
client = py_trees.blackboard.Client()
client.register_key(
"force_threshold",
py_trees.common.Access.READ,
default_value=42.0,
)Implementation-wise, we'd have to be careful, as simply setting the value means this could override an actually set key.
So maybe something that checks if the key is set, else falls back to the default value (if one is set?).
