I'm checking the build against an internal iOS 11.0.x SDK to make sure there aren't any surprises when landing this.

Already checked using Mac OS X 10.12.x.

We try to limit the differences between upstream libwebrtc to the minimum since we want to regularly update our own copy. And libwebrtc is still evolving a lot, files get moved all the time.

Ideally, these changes would be upstreamed.
As long as this is not done so, the best approach might be to special case libwebrtc.
I cannot promise to keep them except if EWS bots bring compilation errors.

What's the process to get changes upstreamed?  Do we open a bug on crbug.com and post a patch (like ANGLE)?

Yep, there will be compilation errors if the changes are reverted.  Easy to re-fix.
