Returns details on the status of network-wide consensus rule changes, including those currently active, locked in, or upcoming.

How is this used?

You're part of a community that decides on new rules or modifications to existing ones through a collective agreement process. To make informed decisions or understand the current state of these rules, you would need a reliable way to track which proposals have been accepted, which are pending, and which have been fully implemented. In the Bitcoin network, the 'getdeploymentinfo' command serves a similar purpose for tracking changes to consensus rules, which are implemented through mechanisms like soft forks.
