Is this business for sale?

Sometimes as your codebase grows it is hard to know when parts of your codebase can be retired. This issue impacts dynamic languages like Ruby/Javascript where it can be difficult to statically analyze code for such problems.

I have an idea for a product that would monitor your code as it runs in production with the intent of identifying code that is no longer called. The tool would then open PRs on your codebase to:

1. add tracers to give confidence the code is truly unused, and; 2. remove the code no longer being used.

Obviously, security and performance would be paramount.

Is unused code something that your team is concerned about? Would this be something people would be willing to pay for on an ongoing basis?
