It seems that this was settled as fine as-is; if you ever wanted to
allow this to be specifically enabled, you'd have to do three things

1. create a new "feature" in the feature tree. Your patch currently
   uses the "Extensions" feature (child of the default feature);
   you could make your feature a subfeature of Extensions.
2. create a new "component". This should work similar to REGISTRY.path.
3. Add a "FeatureComponents" entry saying that the "REGISTRY.pathext"
   component (say) belongs to the "PathExt" feature (say).

Instead of hooking the environment variable to the REGISTRY.def
component, it should then go to the REGISTRY.pathext component.

The nice thing about this feature tree is that it allows convenient
user configuration yet powerful scripted installation, see

For example, you could set the msidbFeatureAttributesFollowParent
flag, which would make it be selected/unselected if the parent
feature is, yet still allow it to be independent of the parent
for people who really want to.
