It would. However, I expect that we'll need to add support for
approving changes to some options in the future.

If you know of an alternative method of allowing a server to say
that a single copy of an item satisfies multiple subscriptions, please
propose it. In content-based systems, it is *very* normal for people to have
multiple overlapping subscriptions to a single topic or node. The bandwidth
savings that result from using this feature are very, very significant and,
I think, very much worth the added complexity.
