Just a few comments/questions, otherwise LGTM

[Pijukatel]

Nice. Please also remove a portion of the ErrorTracker-related code that becomes redundant with this change.

[Pijukatel]

As far as I understand this change. This should now be redundant,

So all this can be deleted and also the whole early argument and all its usage (_early_reported_errors) . ErrorTracker is private, so such a change is fine.

        # Collect data in case of errors, before the page object is closed.
        if error:
            await self.statistics.error_tracker.add(error=error, context=context, early=True)
