I think 30ma is about normal. There’s a good reason, in an average socket ring (or even radial) you will always get SOME leakage. So there’s always going to be a common sense allowance made depending on whether it’s a single socket, a small radial or one or more rings.
Sure, but as far as I could find, even those have trip rating of 30mA. But perhaps I could find some with lower rating.

Yes, and 30mA, even at mains voltage, will not kill someone. Static shocks can vary from 1,000V to 500,000V and are usually around 5mA for reference.
