Before I looked at the source code it was never really clear to me what MaxHousekeeperDelete actually does.
Now, if I understand it right MaxHousekeeperDelete limits only the deletion of data related to already deleted items and isn't considered by the other housekeeping tasks (e.g. removing outdated history and trends of existing items).

It would be nice if the documentation point out more clearly which housekeeping task(s) consider MaxHousekeeperDelete and maybe which tasks don't.
