If you announce an encrypted stream others can see the fact that you're
announcing it (because, well, you are), but cannot see the content.
Unless you mean to encrypt the announcement itself, in which case people
can see an announcement but cannot read what it announces. You are
perfectly right that for preventing others to see the stream you need
encryption, but to limit the distribution regardless of encryption is a
useful option too.

Pierre is proposing the latter; to limit the announcements in a way
that others don't see the announcements by simply not giving it to
them, rather than limit their ability to decrypt the stream or the
announcement. This is weaker, but still useful.

In fact, it would be nice if we had options for both.
