We can add an option, no problem.

Could you explain, then, why you customized help-key-binding to look 
like default? For example, the below customization would make it 
relatively close to how brackets look (but of course not exactly the same):

(set-face-attribute 'help-key-binding nil
                    :box '(:color "blue" :style released-button 
:line-width (6 . 0)))

And the two places where this face is most prominently used (the one 
under discussion, and 'M-x describe-bindings' output) seem to use the 
face fairly similarly, so it seems to make sense, no?

Anyway, if you want the option, can you suggest how it will be called? 
Will it be just boolean?
