No, that's exactly the problem. The balkanization of the OS platforms
only amplifies this; "non-core" functionality such as IOS's incredibly
rich SNMP support is simply infeasible without the combined support of
a broad base of platforms.

I would eagerly and enthusiastically embrace NX-OS if there was an
interest in consolidating IOS/XR/XE in that direction. 

XE is the most promising migration path, IMHO, as they've embraced
modularity and a proprietary forwarding plane, while still providing
commonality with the control plane (I believe it is still that team's
intent to regularly re-sync with 12.2S for management features).
