autodiscovery without templates is dangerous

This may be a repeat (perhaps even my own repeat), but I ran into this again today and it is a great example of why AD without device template support is dangerous.  Failing to discover things that SHOULD be there is dangerous.  Simple example from a Cat3750E stack:

CMD: show env power all [timeout = 10]
SW  PID                 Serial#     Status           Sys Pwr  PoE Pwr  Watts
