No... things like DBMS_PIPE are just general tools that can be used
for anything. My point is that Oracle found they needed functionality
like that do provide a feature they were writing (such as
replication), and said "Well, if we need this, there's probably
others that need it too", so they made it all available. Granted,
they may use some internal interface to it that's faster, but they
still provided it to everyone.
