For example, the core (and GPU) temps on my system are just about always 55C +/- 2C, so why am I required to have a graph whose scale goes from 0 to 60?  I was hoping it might auto-adjust the low limit on the scale once the graph filled, but it did not.

But I think I can figure that out if you don't think there's any value to graphs that aren't generally a flat line, um, sorry, I mean if you don't see the value in this option.

The graphs do autoscaling automatically, this is an RRDtool feature. The 
problem is that some graphs plot a zero value when there is not value to 
plot and that forces the graph to scale from 0 to the maximum value 
represented.

This behavior is accepted in the majority of cases. That's the reason 
why not all the graphs include the option 'use_nan_for_missing_data' 
which forces to use the value NaN when there is no value to represent.
