This field is: * Unsafe in presence of Oilpan (see https://crbug.com/40261265) * Not actually used - there are no callers of `AgentGroupScheduler::GetBrowserInterfaceBroker`. This method was added in https://crrev.com/c/2677585 and AFAICT no callers have ever been added later - for example this command finds no other commits: `git log -S AgentSched -- content/browser/browser_interface_binders.cc` Removing this field also helps to make progress on https://crbug.com/41482945 - this field is related to 1 out of 5 callers of `BrowserInterfaceBrokerProxy::Bind` and the linked bug requires passing `ContextLifecycleNotifier` to `HeapMojoRemote`. I note that `AgentGroupSchedulerImpl::BindInterfaceBroker` seems to be the only caller of `BrowserInterfaceBrokerProxy::Bind` which doesn't have a 1:1 relationship with a `ContextLifecycleNotifier` (which IIUC roughly corresponds to the `ExecutionContext`). The other callers are 1) constructor of `WorkerGlobalScope`, 2) constructor of `content::RenderFrameImpl`, 3) `MojoBindingContext::SetMojoJSInterfaceBroker` (we ignore here `GetEmptyBrowserInterfaceBroker` which doesn't actually need to bind an actual mojo remote).
