If it's going to make things faster and it's just exposing an existing method 
i'd say go for it, after all people are committing patches that are 200 lines 
wrong and breaking the build and adding stuff that could be argued that are 
features so there's no need for you to hold back of what seems a really small 
thing (though we haven't seen the patch).
