Where is the best AIX SNMP support?

The community developed AIX SNMP Zenpack at http://wiki.zenoss.org/ZenPack:AIX_SNMP is labelled V1.1
Github mentions V1.3 https://github.com/zenoss/ZenPacks.community.AIX (but this forum points to 1.1)
V1.3 looks promising, but I don't know my way around github.

Zenoss commercial SSH based AIX Zenpack was working but SSH is deprecated at my shop
Zenoss commercial template Devices (Server/Linux) yields file information, but none of the CPU info found under graphs.
Are there a tweaks to the snmpwalk reply processing that I can implement

Any personal experience out there
Should I go after Zenoss commercial support to "fix" this, or is there a good Zenoss community solution
