To be honest, that's something that needs better automation anyway.
Epoxy and Mesa want to track the xml updates closely too. I've set up
cron jobs in travis to check daily whether the xml has been changed, so
I'll at least get notifications:

https://travis-ci.org/nwnk/OpenGL-Registry
https://travis-ci.org/nwnk/EGL-Registry

It would be good to close the loop there and automate the process of
importing the XML, rebuilding, checking for ABI breaks...
