Thanks for the headsup. I can fixup v3 when I respin.
However, I've always interpreted this binding as follows: - cooling-maps should be mandatory for active and passive trip types otherwise there will be no cooling - cooling-maps make no sense for critical trip type since we're invoking system shutdown - cooling-maps are optional for hot trip types.
Is this your understanding too?
We should be able to enforce this in YAML.
