Do we need to still set 'compatibilityVersion' at all, and should we still
support the other old ones?

Any plan to land this? Or should it be closed?
Removing self from reviewers since I'm cleaning up my incoming review queue.

BTW, gyp moved to git instead of svn. It looks like you CL is based on svn gyp
repo, so you may have to close this issue, recreate your repository and then
send back for review.

mark@ do we need compatibilityVersion at all, anymore?

[Mark Mentovai, 2015-03-10 04:31:13]

If Xcode still sets it when it writes project files, we should too.

[justincohen, 2015-03-10 19:29:41]

I put back the hard coded 'compatibilityVersion' of "Xcode 3.2" (that's what
Xcode does now).

But I kept the removal of the ability to customize that value.

WDYT?
