Any plans to improve pings on certain champ abilities?

There are some passives, like Corki's Package, that allow you to ping their cooldown. Will all champs eventually be able to ping such things? The main one that comes to mind right now is Malzahar's Void Shift. Sometimes when my jungler is approaching I'd like to ping to wait a couple more seconds for my passive shield to be ready but am unable to do anything. Some abilities and ultimates are not affected by pings either. Shyvanna has no choice but to ping her Fury bar because you are simply unable to ping the ultimate. Instead of "not ready yet" it just doesn't have anything. Since her Fury is only used for her ultimate anyway, this should be as easy fix, right?

There are several others, but those are just the ones I've personally experienced recently. Anyways, just wondering if anyone knows (or if Riot could answer) if these types of pings are in constant development or if they're done with this feature.
