Hi, the first things I thought of here is pages you are browsing snooping on or hacking other browser pages, e.g. ad payloads across multiple open pages communicating in realtime in their tracking of you. Could that be a major change in the abstraction of independence/encapsulation of web pages, or in other words a break against user protections in the contract of using a web browser instead of applications. So, please keep security and privacy as first order design considerations with this :)
