:) Structured data exists regarding many other subjects such as books and magazines. I would think that a similar approach could be taken to technical debt. I realize that development tasks have properties and interactions that change over time, but I think that having a better quantitative understanding of the backlog would be good and would likely improve the quality of planning and resourcing decisions.
To use an analogy, as far as I know there is no project management system that reliably produces accurate estimates of the time and resources required to complete large projects, but I think that attempting to use a project management system is, in many cases, better than trying to execute a large project without a project management system.
