Splitting the value into several pieces has the advantage to make you
compliant with any SNMP engine on the world but introduces not only
costs for application reassembly but also opens a can of worms wrt.
atomicity of operations. In fact, atomicity and the implications of a
lack of atomicity if you have to split a single logical operation
(which might in the general case include multiple related objects
anyway) into a sequence of operations is what makes a management
application writer go crazy and turn away from SNMP as soon as he/she
can.
