From the reference: "GOAMD64=v3: all v2 instructions, plus AVX, AVX2, BMI1, BMI2, F16C, FMA, LZCNT, MOVBE, OSXSAVE."

Were those supposed to have been included? What of those is not emulated by Rosetta?

I'm struggling to understand the chain of following how this results in us not having nice things?

Iiuc, paraphrasing, sounds like go made an assumption about user requirements, that turned out to not be true when the arm macs came out? Wouldn't the arm mac users of go prefer to have docker images that dont need to be emulated anyhow?
