Maybe better put: Bazel (and its predecessor) do support Go, but they don't support the traditional directory structure-to-import path semantic that we've come to expect in the outside world. And even then, the terminal directory needn't match the package name, but accomplished Go developers seldom violate that convention these days — thankfully.
All of this makes it paramount for developers of Go tools to use a first-party package loading library like package packages (https://pkg.go.dev/golang.org/x/tools/go/packages), which can ameliorate over this problem through the specification of a GOPACKAGESDRIVER environment variable to support alternative build systems and import path layouts (the worst thing someone can do is attempt to reverse engineer how package loading works itself versus delegating it to a library like this).
