ReadBuildInfo.Main.Version shows "(devel)" after tagging v2 package as v2.
package main
import (
"fmt"
"runtime/debug"
)
func main() {
info, _ := debug.ReadBuildInfo()
fmt.Println(info.Main)
}Although my personal case may be different - I'm not 100% sure how I broke this feature in my private repo - the scenario below successfully reproduces the same output, so I think it's still worth reporting.
Thanks to user truck.dad from the Discord Gophers server for his initial support and the Unix PoC!

or pseudoversion, or literally anything other than "(devel)"
