The benefit of this approach is that rather than having these defaults and fighting against them, it’s fully up to you to decide how to handle everything.

you have less direct control as you must rely on the vendor’s adherence to IAB’s guidelines for compliance.

Directly blocking the vendor scripts (using another prior blocking method), then executing them only after consent has been collected. This method requires more implementation work and it’s a bit slower in terms of execution time, but it allows personalized ads to be served from the first page view (where consent hasn’t been collected yet) and gives you more direct and solid control in regards to ensuring compliance.
