And I swear I wrote the previous mail before I read this announcement:

https://fsfe.org/news/2017/news-20171108-01.en.html

But the actual practices there are pretty much what I'd expect as a
start (plus a list of acceptable licenses), they even use the same
identifiers as you are adding, but they also back them up with the
actual license texts in the source tree, which makes them a whole lot
more useful.
