So if it makes no noticable difference, is it a problem?

Obviously the "containment" at Oklo lasted a hell of a long time, and
it probably isn't the only site where this has happened.

The idea is that we can in fact dispose of waste products in a place
that has been stable for millions of years, and after 10kyears, a
geological "moment", it decays to safe levels.

Remember too that geology isn't coin flips.  A site that has been
stable for a long time is very likely to remain so.
