Should another user post another answer, instead of commenting, in a language that already has answers from somebody else, in the following circumstances?
- It is a modified version of the current answer.
- It uses an entirely different algorithm, etc.
- Part of the new answer is a derivation from the first one, and part of the new answer utilizes another algorithm.
My personal idea is No for the first one and Yes for the second one. However, what about the third one?

Do we already have a consensus on this? I cannot find up-to-date posts after a bit of research. The only thing I come up with is mniip's idea from 2014.
