VS Code 1.132 puts Copilot, Claude and Codex behind one host, and removes the policy admins used to turn it off

The agent host is the structural change. It runs agent harnesses "such as Copilot, Claude, and Codex in a dedicated process" on a published Agent Host Protocol, lets you reach one agent session from several windows, and puts a harness dropdown in the editor. Microsoft describes it as rolling out progressively.
The deprecations remove the ChatAgentHostEnabled policy,
and the notes say what that means without softening it: administrators can no longer
centrally disable the agent host through policy. The per-developer setting
chat.agentHost.enabled remains, so the control has not gone away, it has moved from
the administrator to the developer.
Why it matters: A protocol with three named harnesses behind it is the first sign of harness portability arriving as infrastructure rather than as a wrapper script. The deprecation is the more urgent half: a removed admin policy disappears silently on upgrade, and nobody files a bug when a restriction stops being enforced.
