For me, this is not an overlook and given that the interface RandomGenerator is open (anybody can implement it), 
this does not seem possible. 

If you read the doc of Random.from(), this is clear that a RandomGenerator is not serializable by design 
[ https://docs.oracle.com/en/java/javase/23/docs/api/java.base/java/util/Random.html#from(java.util.random.RandomGenerator) | https://docs.oracle.com/en/java/javase/23/docs/api/java.base/java/util/Random.html#from(java.util.random.RandomGenerator) ]
