With my original fix of just allowing buffer-local binding to appear in help-quick, I fully intended to disable most of the global bindings (I don’t need a reminder of C-x C-f) and expected it to be therefore  a smaller and easier to parse mode-specific list.  

Since the user has to take the initiative to modify `help-quick-sections’ in my simple approach, I do not see “loss of global bindings” as a concern; that’s a feature, not a bug, from my perspective.
