How is that a design fault ? It was purely a poorly chosen configuration setting which reflects the fact that Mongo was originally not a general purpose database. And it was never even an issue for 99% of people because all the drivers at the time used the safer settings.
I always find it amusing when people bring these issues up because it's like a giant sticker on their forehead that says "I've never actually seriously spent time with MongoDB before". I always go through the configuration of the database I use to make sure it meets my needs. Only seems sensible.

Thats dubious. 1.) When MongoDB was released, none of the drivers used the "safer" settings. 2.) 10gen, at the time, released benchmarks with the "unsafe" settings comparing it to MySQL and boasted that MongoDB was much faster (ignoring the fact that it wasn't acknowledging your writes).
