postMessage with star origin issue

Hi, 

We are using the PowerApp SDK from https://apps.powerapps.com/apphost/clientsdk?version=1

And we saw it is using postMessage with star as target origin.

It has security concern with start origin with postMessage function Window.postMessage() - Web APIs | MDN (mozilla.org)

Is there any plan to specify the exact target on the later version of the SDK?
