Previous text is documented everywhere and describing usual good
practice, so it should remains in place, in that means r304928 should be
reverted, because replace proper way of doing things with obsoleted
feature description.

What I suggest is not _replace_ old text with new, but _add_ new text as
describing current and not recommended way, with the direct mention that
this feature is obsoleted and not recommended for relay on it.
