I think that would work well enough.

Although I might quibble about what 'local' means here. If the src block 
is under a headline called XYZ with a `header-args' property of `:eval no' 
and the babel call is under headline ABC with no header-args 
property, I think some would expect the default to take precedence for 
calls under ABC over the property in XYZ.
