I'm happy with the approach here.

At some point we should put version numbers into the target features, but I think that can wait until we know how to cope with how the `G` extension expands into its other extensions (this has some open questions in general). This suggestion does not, in my mind, block this patch, as including `experimental-` in the target feature names does make it clear which features are experimental today.
