This is most likely a wrong perception. There are basically only two
locations where SNMP modules are registered in the IETF: under mib-2
and under transmission (yes there are a few exceptions but overall in
number they do not matter). There are close to 240 MIB modules below
mib-2 and about 50 MIB modules below transmission.

RFC 4181:

   - The value assigned to the MODULE-IDENTITY descriptor MUST be unique
     and (for IETF standards-track MIB modules) SHOULD reside under the
     mgmt subtree [RFC2578].  Most often it will be an IANA-assigned
     value directly under mib-2 [RFC2578], although for media-specific
     MIB modules that extend the IF-MIB [RFC2863] it is customary to use
     an IANA-assigned value under transmission [RFC2578].  In the past,
     some IETF working groups have made their own assignments from
     subtrees delegated to them by IANA, but that practice has proven
     problematic and is NOT RECOMMENDED.
