I think we need to be very specific to mention where the focus is applied, either in on the global Internet or on the Network {internal, home, corporate}.
Saying we're shutting down IPv4 scares a lot of people but that's not in scope because on the Network (internally) come to mind right away. The focus is on the Internet.
Abstract
The IETF has stopped working on IPv4 protocol only solutions that are specific to global Internet.
The IETF has stopped working on IPv4 protocol solutions except where needed to mitigate documented security issues.
The IETF has not stopped working on IPv4 protocol solutions to facilitate the transition to IPv6, or to enable IPv4 decommissioning on the global Internet.
The IETF has no 'plans' to decommission the IPv4 protocol on the Network {internal, home, corporate}.
