How to use embark-bindings as a drop in replacment for describe-bindings

[Thaodan]

Hey,

I'm using embark-bindings as a drop in replacement for describe-bindings which does work quite well mostly..
However some modes such as Gnus-article-mode has it's own function to describe-bindings which
then calls the real describe-bindings.

Previously I have used helm-descbinds, for which this isn't an issue as it overrides describe-bindings.
What would be the best approach to do the same for Embark-bindings?
