Having slept on this, I'm still not completely comfortable with suggesting that the official way to get f is via the objective because there seem to be details that change depending upon where it's defined.
Maybe it would make sense to add a struct which explicitly contains f, and whose evaluation is defined to compute the objective? i.e. formalise the API.
Yeah I was wondering something similar. would you be up for proposing a way of doing that in a separate PR?
