If you ask Daniel Micay he will probably give you a very good explanation of why root access is a bad idea. I am not sure though and can imagine its sometimes helpful and might be safe if you totally trust the root app like Magisk.

But not every module some random person on the internet writes is safe or makes even sense. For example changing IMEI, IMSI etc. is not possible for the apps that actually use it, i.e. cell connectivity.
