Assuming that command-line parameters are actually globally visible on
your platform, which isn't necessarily the case.
Anyway, I basically agree that the legitimate use-case for this feature
is pretty small, and it is probably worth removing. However, I don't
think it is urgent (there are plenty of other ways to shoot yourself in
the foot), and shouldn't be backpatched -- people may be using this
functionality.
