I stopped airplane maintenance software from shipping with a particularly egregious form of this for SSL session key generation. It’s hard to get a good random seed on a real time operating system. I tell you hwut.
Depending on access to sensor data, it's possible to use a mix of various sensors as well as the time for seed generation. Though baseline static from RF is better assuming that is possible as well.
Of course, it's always possible for something to do something stupid, like weak rng.
