BTW honest question - what is the idea behind not running ember in production mode with `-prod` ?

We use the `EMBER_ENV` environment variable instead of the `-prod` flag. The result should be the same. I certainly see a production build running here on Meta and other sites.
I’m not sure what’s printing `Environment: development` to the build log… we should investigate 👀

I’m also showing environment development when upgrading discourse.

It shouldn’t make any functional difference… but here’s a PR to use `-prod` and therefore fix up the logging:
