Quite. I think this is simply a bug and it should wait for the domain to be destroyed. It's IMO a tolerable side-effect if this means that when the domain shuts down in a way that causes it to be preserved (ie the daemonic xl doesn't reap it) xl shutdown -w gets stuck. (There should be an option to restore the former behaviour but it should not be the default.) Ideally xl would record something somewhere so that it would know what's going on and could make "xl shutdown -w" fail in the default case if it's going to wait "forever".
