Is this command really necessary? I do remember the days that NMSs would use the ifindex number to label interfaces, and in a modular chassis keeping track of which index was which interface was a real pain in the ass. It seem like most NMS these days use the interface identifier (fa0/0, s0/0 etc) to label interfaces so if/when the index # changes it doesn't really matter.
Like you say, it really depends on the NMS in question as to whether or not it's really NEEDED. For example, MRTG has the flexibility to use any kind of unique identifier to track interfaces, so ifIndex persistence is not needed for it. However, to be completely compatible with all potential NMSes, it doesn't hurt to enable it. It will just take up a few extra bytes in protected NVRAM.
