Indeed we can recommend people not use it and tell people to avoid using libraries that are using it, and if they still do tell them to *really* be careful about it. All this not because we think the *feature* is bad, but because the *implementation* can easily lead to user error.

This happens to be the exact same advice as for the original error_handler and libraries that rely on error_handler modifications - although the risk of collateral damage is much smaller with $handle_undefined_function...
