Well, that is true for several NSI features. If we limit ourselves to the
intersection of what everyones NRM supports, our feature set is going to
be very narrow.
However, what is almost sure is that someone will implement NSI and not
support release because their NRM does not support it. The interesting
part is that this system can still provide a useful service. So I do see
your point.
I don't really have a clear yes/no stance here. The timing is pretty bad
though.
