It's a research paper. You can write a theoretical paper and let others apply it practically, which others can figure out the practical aspect and report results of benchmarks, or others can also build on the theory.
This paper only has 2 authors. The other solvers are probably applying technique specific tricks and speedups, and you're working with approximate optimization, it's not that easy to move everything over.
