The "description" cmd can have strings as large as 300 characters. It is not uncommon for customers to use its content to include service provider, their Tel#, ckt Id, destination and such.
The contents of this cmd are used via SNMP as defined in RFC 1213, a very very old and well established MIB. Adding one more cmd would create problems on the SNMP instrumentation front.
