I just saw the suggested edit.
It was rejected by the community 2-1 and I agree with that decision.
I also agree with Eliah, but I'll add notes specific to the case:
- My answer wasn't so long that somebody might not notice the second. That's one of the few cases where summarising other answers into a header answer might be acceptable... But there was simply no need here.
- Proper attribution wasn't made.
- Perhaps most importantly, it's a different answer. Streamlining an existing top answer using later answers' techniques might be appropriate, but this is adding an alternative technique. Again, no need for any of that here, that's exactly why we can post multiple answers.
