You only have the check for the enum, not the definition of the
replacement one here. I guess you want to squash patch 2 in here?

We check for the availability of the new function and the enum
containing its possible return values separately: is there a chance
we might find one but not the other? I'm hoping not, but it would be
nice if you could confirm that's indeed never going to happen, as it
would be quite problematic if it did...
