Is this a new property ? I'm not fan of adding yet another of those
silly arrays.

I would say this is the right time now to switch over to a node per
state instead, as we discussed with Vaidy.

Additionally, while doing that, we can provide the versioning mechanism
I proposed so we can deal with state specific issues and erratas.

Cheers,
Ben.
