subagent extensions and master agent extensions are two kinds of agent extensions.

Whenever there is a need to modularize the implementation
of management capabilities.

Subagent extensions make the most sense when there is a need to support
components from multiple vendors, different lifecycles, system-specific
constellations of components, dynamic addition or removal, to name a few.

A MA agent extension makes sens for modular capabilities best implemented
within the master agent.  For example, implementation of capabilities like
the notification log mib, or extensions to USM, would probably make most
sense implemented as extensions to the master agent, rather than in a
distinct subagent.

That's not surprising, since 2741 is about subagent protocol.

A lot of useful information on the background and motivation for subagent
technology is available at
