To clarify something here, by "evil", don't necessarily think "binary only".
Out of tree modules are frequently using symbols that they shouldn't be.
Because they get no peer-review here, they 'get away with it' for the most part.
Until distro vendors push rebased kernel updates that removed exports that
should never have been exported, and suddenly people like me get bombed
with "Fedora broke my xyz driver" mails.
Reducing the opportunity for people to screw things up is a good thing.
If a symbol is exported, most out-of-tree driver authors seem to
think its "fair game" to use it.
