I think most dealers would probably do this as a courtesy, it was ages ago but we sure did, and i know that they do "trip checks" for free now.
I doubt anyone would keep track or start an oil consumption test without excessive oil consumption being mentioned.
Another aspect of this that no one thinks about is that buy including maintenance free they have complied with the provision of MM that says they can't require you to use their product unless it is supplied at no charge. I haven't heard of it happening but all it takes is the right person rubbing the right person the wrong way and one said person finding an aftermarket filter on other said persons car....
they could probably make it stick too...
