Perhaps the death of SNMPv1 and 2c. But net-snmp, or v3, will live on. It's a little like IPv6, in that it's been around for years (I wrote a paper on SNMPv3 for SANS 10 years ago) but it's still not widely adopted. A shame, that. v3 fixes most, if not all, of the security gripes about the previous versions.
I think that it's helpful to speed up the adoption of v3 if Microsoft drops support for (or partially obfuscates) SNMPv1/2c.
