It would require a dev every time someone wants to track something new.
It would require rerunning ci/cd, testing, qa to bake it in, in case it fails and breaks something.
All of that is hours of resources which translates directly into money.
With GTM, planning still occurs, organization, but someone can try something, have a debugger to iterate on, once done, hit publish. No need for dev, testing, qa, ci/cd time, breaking, reverting, etc.
