That's what I wanted to say; there's always some risk that passwords get
accidentally printed to the screen, and that someone (even if
high-priviledged) doesn't *want* to see them.

thank you for this summary. I think the same, and hope that this (or some
similar) patch gets committed.
However, I believe that this won't happen, as I've already seen a few +1 on
leaving things as they are (JE, PL), so I fear that we (non-core-team) people
will be voted down.
