Previously various information was only available for directly attached
servers, since it is communicated via PROTOCTL.
Now, we will also communicate information about leafs behind us.
IRCOps can use the /SINFO command to see these server features.
Services codes don't need to do anything, or at least are not expected
to do anything. They can still receive the information and do something
with it, of course...
Read the following technical documentation for full information,
as it will outline very specific rules for using the command S2S:
