But `go generate` can, and that is required to build some go projects.
It is also somewhat common for some complicated projects to require running a Makefile or similar in order to build, because of dependencies on things other than go code.
The culture around "go generate" is that you check in any files it generates that are needed to build.
In fact, for go libraries you effectively have to otherwise `go get` wouldn't work correctly (since there's no way to easily run `go generate` for a third-party library now that we're using go modules, not gopath).
Have you actually seen this in the wild for any library you might `go get`? Can you link any examples?
"go build" of arbitrary attacker controlled go code will not lead to arbitrary code execution.
If you do "git clone attacker-repo && cargo build", that executes "build.rs" which can exec any command.
If you do "git clone attacker-repo && go build", that will not execute any attacker controlled commands, and if it does it'll get a CVE.

In cargo, "cargo build" running arbitrary code is working as intended. In go, both "go get" and "go build" running arbitrary code is considered a CVE.
