As for the second question - OK, I can live with that. It was just a "it would be nice if" type question.

And for the first question, I cant see any way to implement level_free in my situation.
So there is no definately other way to free a selected entity's nexus usage other than level free?
Because my entities are elements of a self-creating, flowing landscape, created in an empty level. So I cant use
level_free to remove old entity-space because I now have new, living entities that have been created since
my last proposed level_mark.

Any ideas or suggestions? (yes this is stretching the topic a lot)
