These are integrated chips where the the user host code runs on the same chip, I think even in the same address space. So if that is compromised, the Bluetooth side is compromised regardless of the existence of the vendor commands.
In principle you could use an ESP32 as an external Bluetooth controller exposing HCI of course, and then the concern would apply, but I don't know why anyone would do that when dedicated Bluetooth chips designed to be used as HCI dongles exist.
