Is this future proof for >= 1.19?

It looks like it is. I tested this by adding a test_go118.go to an existing project:

//go:build go1.18

package main

import "log"

func init() {
        log.Println("1.18")
}

Running this with Go 1.19 printed the line. Flipping it to //go:build !go1.18 made it go away when compiled/run with Go 1.19.

Any chance this is going to get merged anytime soon? 🙂

Would it be possible to add vcs.modified?

I've seen this returned as a separate parameter, this is basically checking if git was in a dirty state at the time of build.

changing the API is out of scope here I'd say, as we see revision as one. it should still be pretty easy to parse as modified is not a valid git hash
