Comment (by herbygillot):

 As of this moment in time, both `go-devel` and `go` are at version 1.20.4
 (Go 1.20 branch).

 Go requires Go to build.

 The last version of Go that could be built from scratch with a C compiler
 is Go 1.4 (the `go-1.4` port).  Go 1.17 is the last version of Go that
 could be built using `go-1.4`. From Go 1.18 onward, you must build using
 Go 1.17 or higher. (https://github.com/golang/go/issues/44505)

 For Go 1.20, we build and bootstrap it using a downloaded binary of the
 same version of Go.

 Older versions of macOS lack certain API functions and capabilities that
 Go 1.20 expects, so the downloaded binary fails to execute.
