@mikegerwitz Thanks for explaining. I see the point. Although I never understood the SPDX identifier as a list which helps you to chose a license for your project but rather as a machine readable identifier you add after you have chosen a license. A list which help you to chose the license should be much more descriptive than just a name, also gplv3-only would be to short in my opinion. Therefore I'm not sure if this change solves a real problem. But anyway, I got the motivation for the change.
