NOTE
Netty Bind Source: Initializing the Channel
Applying options, attributes, and pipeline handlers to a newly created server channel.
This is a historical learning note and may contain outdated or incomplete understanding.
Channel initialization applies bootstrap configuration to the new channel: options/attributes and the pipeline handlers needed for subsequent events. A server bootstrap also installs logic responsible for initializing accepted child channels.
The important separation is parent/listening channel configuration versus accepted child channel configuration.
Exact initializer classes and when each option is copied are internal details; use documented bootstrap methods for application behavior.
