If there is no relevant MIB, the discovery doesn't go beyond classification phase?

in below docs

SNMP Discovery explained - Support and Troubleshooting

ServiceNow says "If there is no relevant MIB, the discovery doesn't go beyond classification phase?"

Why so? 

For a custom pattern, I know the which OIDs to use. Its documented by vendor. I will use SNMP query in pattern and fetch the result. Why do I mandatorily need the MIB file in this?

so as per ServiceNow, since i did not load the MIB file, will discovery stop at classification phase only?

i dont

@doug_schulze Thank you for replying.

"Also, you see from this screen shot above, technically you dont even need a MIB if you already know the OID, the actual dotted number." - this was exactly my point/question that is not really mandatory to load the MIB as long as you have the OID details already handy with you.
