Why would one use such a module instead of the "pure" nrf52832?

Using pre-certified FCC module does not dispense you from the require certification. You can only reuse the intention emission test results. You are required to FCC/CE certify the product as a whole no matter the component inside is certified or not. The certification of the module is valid for you only if you use it as it without any addition circuitry. So pre-certify module is more or less for marketing purpose.
Right, I've seen similar troubles on one project. So the consensus among "smart guys" is to have RF expertise or some external consultancy, work with custom PCB design including BLE part, tune specific antenna for each product version and certify it then one by one?;)
