This suggests that all such variables should be considered obsolete,
since eval-after-load is cleaner.  I think I agree, but I have only
ever used eval-after-load so I might be missing something.

I would suggest to declare the above variables obsolete and point
users to eval-after-load instead.  Does anyone disagree with that?
