What kind of testing have you done with this?  Have you tried a full 
world build?  This kind of change scares me a little as what issues we 
might have patched around or behavior built into software.

I just completed a world build locally and have failures in file-native 
guile-native, and gtk+3, not sure if we need to invalidate sstate, I am 
starting a clean build.

I have not dug too deeply into this yet.

Sau!
