I've been fiddling with the mass settings on the duplication engine, and it's pretty good, but I find that often I have legitimate reasons for writing code twice; namely, it would be needlessly obfuscating code to refactor a given pair of functions.

Is there a way to configure the "count threshold"? Currently this seems to be hard coded at 2: if code happens twice, it is reported. I'd like to be able to configure something like this:

  duplication:
    enabled: true
    config:
      languages:
        ruby:
          mass_threshold: 10
          count_threshold: 3

This would emulate the "rule of three" in Ruby while being extra-strict about code mass.

If this is interesting to the core team, I could potentially even write a pull request.
