It's not just "historical precedents in the Go community" it's "ongoing in Go itself": Go's developers will try as hard and as long as they can to perform raw syscalls even on platforms where it's not officially supported, and even on the one platform where it is genuinely actually supported they'll do raw vDSO calls (which are not) which predictably blows up (https://marcan.st/2017/12/debugging-an-evil-go-runtime-bug/).
