Simple and fast question here: are we using the same tag people-picker for both the old PeoplePicker and the new ClientPeoplePicker? This came to mind after reading the question SharePoint - How to clear PeoplePicker field with button click? - some users actually didn't notice that the question is about the new control, and as you can see the solution is different depending on which control you use.
Are there any preferred community standard at handling situations like this one? Should we create two different tags or one is enough to encompass both controls?
