That patch only solves one possible source of the problem.  There are
others, which are likely affecting you.

I agree.  I would be in favor of putting strong warnings in the

remove it from the codebase entirely for backwards compatibility
reasons.)  But we should hear a consensus from the community before
proceeding down this road.
