What I like about agile and its fellows is that it takes old ideas and turns them into one-click tools.

My theory of software development process is that tools are the dominant shaping force.

Waterfall was a fit for the word processing era. Build a big document, hand it off. Changing the document is a pain, so write it once in advance. And so on.

The advent of bug tracking tools showed how individual work packets could be packaged, sliced and dealt with individually.

Similarly, this tool revisits the ideas of traceability (previously achieved with spreadsheets, basically) and change matrices / change ripples. Because it's automated, it actually becomes part of the process, rather than an impossible burden.
