				wraitiiUnsubmitted Not Done Inline Actions I think it'd be better to keep manual traces here, but I don't remember if we still have code doing that. `PersistentRootedObject` is easy to use but incurs a performance cost for all further usage, and not really that needed (we could keep a tree of files or something). This can be added as a TODO if you'd prefer not do that now, I think. wraitii: I think it'd be better to keep manual traces here, but I don't remember if we still have code…
