### Describe the Feature Request

Currently you have to use ion-content (along with other optional root elements) to navigate to and from a view.

It would be nice if instead I could use any root element, such as a div.

if needed, maybe the root element could be given some type of tag that the navigation system could use, for example `

The issue does not identify files, tests, or an entry point. Start by locating the navigation code that requires ion-content and determine how arbitrary HTML roots would be recognized. Done means views can navigate without ion-content while existing navigation remains supported.
