Notes:
1) sysObjectID includes SMI PENs, and many SNMP network monitoring systems
use sysObjectID to identify devices, as suggested by RFC1065.
Auto-discovery is especially reliant on these values.
2) syslog (RFC5424) uses the SMI PEN registry.
3) ipfix (RFC5101) uses the SMI PEN registry.
4) sipclf IDs use the SMI PEN registry.
5) middisc ID does not use the SMI PEN registry because it is too large
for its intended use, and requests a smaller (8-bit) vendor code registry.

I am not sure how these uses would be impacted by a PEN larger than 32
bits.
