I don't follow the users list, but I assume there has been some discussion of the technical difficulties of implementing this sort of feature. As a general comment, because of the data layout, adding/deleting RRAs should be easier than adding/deleting DSs.
Instead of implementing this within RRDtool, it may be simpler to implement these functions as utility scripts that manipulate the XML dump. Then restore can be used to generate a RRD file. I have a perl script that deletes RRAs from a XML dump; I can at look at how difficult it would be polish up the code and make it available. I have another script that adds RRAs specifically for upgrading existing RRDs to take advantage of the aberrant behavior stuff I've added to 1.1.x. This script might be modified to serve as a general "add RRA" utility script. Any preference for using external utility scripts versus a new RRDtool function?
