The script should use the hijack/trap/hijack method to queue up all GA commands, with a timeout (from page load, not on each command) to pass them all to the ga library. This would allow a custom gaSpy deployed via GTM the ability to control all hardcoded GA commands, as long as GTM loads before the timeout expires (maybe 8s?).

This method would slightly decrease bounce rate metric of hardcoded tracking, because fewer cancelled loads (accidental clicks) and nearly-immediate bounces would be tracked.
