I see. I will provide a patch then.

Like I said, I noticed some inconsistencies with the behavior of buffers 
like completion, especially when it comes to quitting and/or killing the 
buffer. Most notably help-mode stands out since it has a view-mode minor 
mode, which maps `q' to `quit-window' and `z' to a scroll function. In 
special-mode buffers I can use `q' to quit (and bury) and `z' to kill, 
which is nice. help-mode requires me to set the view-exit-action to 
`kill' to achieve a similar result, but it is still inconsistent. Could 
we make help-mode derive its map from special-mode also? Or would this 
change the key bindings for help-mode too much?

Ok.

Thanks for the explanation. That makes sense now.
