Thumbs up for not using rand, but the assuming that MT is a golden bullet is not exactly scientific; one should just test few RNGs, it may come in that the code exploits some ultra-hidden hole in MT or that some much faster RNG works equally well. Also reproducibility of a stochastic code means that the code results lead to the same conclusions regardless of the seed, not that you get bit to bit identical output for the same seed. In case one assumes (only) the latter, it may end up in seed cherry picking, not-optimizing code because it would "break reproducibility" or not investigating the natural deviation of the results.
