I left in 2023. From memory at that time:

1) go kinda eliminates a lot of the reasons for style guides to exist w/ `go fmt` and separately, I think the Go readability team made a conscious decision to approach readability differently anyway,

2) ... once you had a couple people on your local team w/ readability, if your team wanted to do things a certain way, well, style guides and formal readability wasn't really an issue anymore.
