I'm personally using this frivolously in my own footer
```
// vue.config.js
const revision = require('child_process').execSync('git rev-parse HEAD').toString().trim()
const pjson = require('./package.json')

process.env.VUE_APP_COMMIT = `"${revision}"`
process.env.VUE_APP_VERSION = `"${pjson.version}"`
module.exports = {}
```

```
<template>
  <footer>
      <span>v{{ version }} ({{ commit }})</span>
  </footer>
</template>

<script>
export default {
  data: function () {
    return {
      version: process.env.VUE_APP_VERSION,
      commit: process.env.VUE_APP_COMMIT
    }
  }
}
```

# Validation
 - I'm using this.
 - The inline require doesn't cause lint issues on vue-cli v3 config files. I did a full builds to check.

Also, quotes, optional now. interesting. I tried it.
