One of the features of that system (and others) is the ability to specify different "techniques" for an effect with the appropriate one chosen base on the capability of the card. It won't be hard to incorporate support for that, but it will be work to write the techniques for the older systems.
It was also suggested that the PLIB version could be left to support older hardware. That's fine, but aircraft designers would probably like some support for testing what version the user is running.
