because 'q' will eventually start showing old *Help* buffers.
because 'q' deletes the window which I want to keep.

because C-u q is two keystrokes; quite often I keep hitting 'z' until I
get to a buffer where z self-inserts.

C-x v is the vc prefix for me.

> You want to kill Dired but you don't want to use `C-u q'.

the question is whether this is a generally useful binding.
I think it is.

I don't think special-mode buffers are "precious" - they are easily
restored, so killing them accidentally should not be a problem.
Apparently others disagree.

So bind it in dired mode. The change affects all the other special modes!
