If a generation is ~20 years then 50,000 generations is around a million years. We're talking several times longer than recorded history. In fact, I was curious and looked it up - Homo Sapiens is estimated to be around 300,000 years old [0]. We should be so lucky if there are humans around in 50,000 generations. Just by nature of the amount of stuff that happens, if they have any conception of what the UK was or any idea what happened there then there has been some sort of transcendental enlightenment where there are no longer limits on how many memories a human can retain.
In short, I think you are exaggerating the downsides of maybe a potential 10x cost blowout on the budget of a government project and a trivial amount of waste disposal.
