This should be in the documentation then.  One day a user is going to 
complain about this and we need to be able to explain why there is such 
a limitation.  (Ideally the documentation should describe how to 
workaround the problem, if this is possible).

I recommend referencing the PR number in the comment, so that code 
reviewers have a chance of finding out why the keyword is disabled.
