If systems maintain long term stable mappings between the generated IRIs and internal blank nodes, then that will be another way to interact with blank nodes.    (This seems like a bad practice to me, so far, but I wont be too surprised if someone ends up finding it very useful.) 

Very useful. It's hard to deal with real-world FOAF for e.g. without this.

Many triplestores have ad-hoc hacks to make this possible, and Skolem URIs give a common form for it.

It would also be a viable way to represent incremental backups, or patches, but we've not implemented them.
