You claim it is hard to do. However it accidentally happened recently. So it can't be that hard.

After all, if all "security experts" are so good, why didn't they catch the recent fork?

They didn't catch this because it wasn't a bug in the client code itself, rather it was a bug in a third-party library, which is currently being migrated away from. Further (as far as I'm aware) it's only happened by chance, never deliberately by a malicious entity.
