If this new type is created, then you don't need to create an RRA with a step of 1, it will work however long the step interval is. 

This means that all the standard RRA definitions you're using (many people have a step of 5min) will work without change.  In particular, MRTG will be able to use this new data type with minimal alteration, as will other software that uses the RRD API.

While you can manage to approximate this by special configurations of DS and xff setting in the RRA, it is much simpler if you can simply set a data type.  I think this would be a good feature to support directly, rather than via more complex settings...
