Comment (by omarreiss):

 This ticket was discussed today in #core-js on WordPress Slack, see
 https://wordpress.slack.com/archives/C5UNMSU4R/p1515505132000043

 The main concern that was raised was the transition problems that might
 occur in not being able to run WordPress from the src directory anymore. I
 took 3 options from the :

 1) Stop allowing running from src and only build to `/build`.
 2) Allow running from src after a build step but .gitignore the built
 files.
 3) Allow running from src and commit the latest stable version of JS in
 src.

 The general consensus seems to be that we need to have a transition period
 in which we start out with option 3 and after some time transition to
 option 2 and/or option 1. I will do another iteration to make this
 possible.

 I would personally be in favor of `gitignoring` the built files from the
 start, because of the confusion that comes with having a set version of
 build files in the source. This can lead to a myriad of issues that I'd
 like to avoid. If we choose option 2 as the initial approach, the
 configuration / dev workflow impact would be minimal, while the gain would
 still be complete.
