First of all, let me just give praise to how witty the title was. I feel that deserves recognition!
For all the uninitiated: https://www.youtube.com/watch?v=BN1WwnEDWAM
If you give it a listen, you'll notice that the lyrics kinda describe what the DevOps had been up to since the DDoS issues started back in 2023
Anyways, as the song says, if you Go, there will be trouble, but if you stay, it will be double.
If you are indeed interested in learning Go, I think that would be amazing. I'm also going to presume that you yourself see this as an opportunity for yourself to use FAF as a practice target in your path to learn Go for your own personal fulfillment. And I myself support this 100% - that is to say, you should Go with that. Of course, if I'm mistaken in my analysis on motivations, do correct me, but I'm positive there's some good motivation behind it, otherwise you wouldn't bother with your detailed analysis of the problem, and this amazingly succinct brief!
As always, thank you personally but also all the other DevOps boys for all the work you do. Some might see your work as bringing FAF down to its knees, but what you are really doing is keeping us up on our knees in front of the chopping block.
An to end this on a musical note, this one's title should both serve as my viewpoint on both what you should do, and what my qualifications are on the topic: https://www.youtube.com/watch?v=GwpCb0qW-6Y
