The Channel Queries service queries channels for information about them (in
terms of topic and modes) as well as their lists of participants. It does this
shortly after having joined a channel, as a service to all other plugins,
so they don't each have to independently do it themselves.
It is qualified as a service, so while it is not technically mandatory, it
is highly recommended if you plan on mixing in
ChannelAwareness into
your plugins.
