Facility stands for a place hosting machines for industrial purpose.
It will be hard for them to remain as nodes as soon as you intend to map
hosted machines. Nothing more.

Mapping machines and keep the facility as node in the middle of them
prevent to make a correct surrounding relationship usually described with
the fenced perimeter.
Then, you'd better (you're not forced to) mapping substations as areas in
such situations.

That's how OSM use to work for now, it's not a power specific business.
Both facility and machines, areas and nodes are objects.

Currently, power=substation is and will remain valid on nodes.
Once you add substation=*, which is recommended (not mandatory), only
distribution and minor_distribution are valid on a node.

The proposal won't change power=substation definition.

iD doesn't implement the whole tagging scheme and I am currently trying to
fix some of those points about substations.
It's not a reliable reference to inspect what is actually possible
regarding tagging. That's a bit of a problem, causing some confusion :(

Best regards
