I'm not sure that this is necessarily the best place to ask questions about Juniper's future product/software plans 🙂 If this is a genuine requirement, I'd strongly recommend talking to your SE and asking him to open an Enhancement Request. Without an ER for this feature, it is much less likely that anything will happen. This is true for all new features or hardware suggestions. It is ERs that drive the business case.
Sorry for the kind of 'non-answer' but I hope it helps you get the info you're after.
