Dude, chill.

extTable OBJECT-TYPE
     SYNTAX	SEQUENCE OF ExtEntry
     MAX-ACCESS	not-accessible
     STATUS	current
     DESCRIPTION
 	"A table of extensible commands returning output and
 	 result codes.  These commands are configured via the
 	 agent's snmpd.conf file."
     ::= { ucdavis 8 }


It's _everyone's_ subtree. As the MIB says, it's defined in the agent's 
own snmpd.conf file so it belongs to whoever is writing that file! Perhaps 
UCD is writing _your_ config files, I write my own.
