If the development team isn’t already all over this, I’m requesting the new library be incorporated with Duplicati and any new capabilities utilized. I’m not sure whether this library change correlates exactly with what the Duplicati core “retry-delay” option intends. If it does, that would obviously be a simple way to integrate it. If not, I suppose it would have to be a new mega.nz-specific option.
Whether or not this would help resolve the occasional strange behaviors seen when using mega.nz as a Duplicati destination, only time will tell.
