Other information

The current behavior of the navigation API updates the URL and the current history entry immediately when intercepting.
This has been a pain point for early adopters of the API.
This proposal is to make this behavior configurable, allowing the developer using the API to defer the commit behavior and call commit when ready.

We're planning to slightly expand this proposal with one more method: WICG/navigation-api#279 . (It is quite simple in complexity, consisting of a bunch of error-case checks and then updating the destination URL if all those checks pass.)
