Terry,
thank you for the question, also on the mailing list:
What is the name of Macro05/Macro06 ?
The name is "ISO/IEC15434 Syntax for high-capacity ADC media".

I would favor for an automated detection, as it always leads to smaller codes.
This feature is widly supported by Bar Code Scanners.
zint just compares the data and uses Macro05/06.

Thanks,
Harald
