I specifically have the WIP head description include the name of bookmark that it's attached to, if any (emulating git's non-detached head), so can't leave it empty (and generally wouldn't want to, for easy way to identify it, esp. with multiple workspaces). Some push blocker for certain commit name patterns would make sense to look into.
