Hi Christian, feel free to file a bug for that or even fix it.
Nevertheless, I remember nested packages being like a quilt that is to short: If you pull it over your head then your feet will get cold etc... From many conversations with Ed I know that nested packages are not really a well designed and that they can cause trouble even with plain EMF. So if someone sees a chance to change their Ecore if necessary, I'd always vote for that.
