Power enabled in unowned rooms?

[Trepidimous]

Is it by design that un-owned power enabled rooms are possible? I was under the impression that once it was no longer owned that power would turn off. If this is by design is it possible to use power creep powers here?

And example of this is Shard1 W32S19

I mention this because I was working on some enhancements to the creep room claim assistant and in it, I was prototyping a red outline for power enabled rooms. [See image]

You can enable power in non-owned rooms after they became unowned. And the only way to reset it is to claim it, then un-claim it.
