Can we use the feature system to enforce this?

We can for chrome.app.window.canSetVisibleOnAllWorkspaces.

AppWindow.setVisibleOnAllWorkspaces is like setBadgeIcon; I don't think there's
an easy way to hide it, but we make it an error here.

+    error_ = kDevChannelOnly;
+    return false;
+  }
+
+  scoped_ptr<SetVisibleOnAllWorkspaces::Params> params(
+      SetVisibleOnAllWorkspaces::Params::Create(*args_));
+  CHECK(params.get());
+  window->GetBaseWindow()->SetVisibleOnAllWorkspaces(params->always_visible);
+  return true;
+}
