I think  you and I are in agreement, except for one small matter:  I think that it'd be useful to say "module evaluated to false, despite having at some point enabled yield true, which probably indicates a mistake."  If this ends up being onerous, I think it's something we can do without.  But I think it will help users who do what Ovid mentioned doing:  writing all their code in a block.  The feature under discussion is the only one that would really be affected by writing your code that way.  That's why I think it's plausible it's happening.

Why don't we start with just implementing the basic feature and then we have a year to think more about the warning if we want. 🙂

Also, we know it needs a name.  I suggest 'module_true'.  If the feature is on, then this module will be treated as evaluating true.  I don't want to say 'require_ignores_false' or something because that could imply it changes the behavior of "require" in this scope.
