Final comment. You're definitely breaking the ABI with this PR, but I'm failing to see the API breakage. You've added default parameters in all methods you've changed the signature and the methods you've made const are not virtual, so it should be a safe transition no?

@taketwo Any comment on this? Where are you noticing API breakage?

Sorry, missed this question. Yes, this should be a safe transition, certainly not "API breakage". Rather "API change" but we don't have such a label (and probably don't need anyway).
