I don't think so, but maybe it should be worded better on that page. What was meant to say is that the goal is to be compatible enough that an application should see no difference in behavior, and therefore should not apply any workarounds, different paths, and so on. But, if developer wants to detect if it's running under Wine, there's a way to do so, and there always will be.
Yeah. We may think changing behaviour based on whether an application is running on Wine or not is misguided, but we're not interested in some kind of race with application developers to prevent them from doing that.
Ideally EACs users (i.e., game developers) would ask them to please not do this kind of thing.
