Do you have any links to data showing effects on brain temperature from that treatment?

Afaik interest has been low in carrying around enough ice pack capacity to make this viable, and with lacking data for it even working, whereas head-cooling packs with circulating liquid through a cooler takes little space, cools way more efficiently and required no other maintenance after insertion into the patient in the ambulance (and is moved with the patient while continously working).

Overcooling is more of a risk with I've packs than not cooling enough. It's much less of a concern in a prehospital setting though, since we're not with the patient that long. It's more of an issue in the ICU.
