I can tell that you really want this feature, but please take a moment to consider how you can help move this forward in a more constructive manner.
Rather than demanding that the core team work on this for you, describe in more detail your use case and engage the rest of the community here in the details of the feature you have in mind.
Try to build consensus around how the feature should behave and what value it really has.
