in 1998 (or was it 1999) at USENIX there was a paper where Margo Seltzer
and Kirk McKusick took a look at softupdates and logging/journalling
filesystems and performance for certain types of operations.

There are clear reasons why one would want to use one over the other.
Journalling and "Soft" metadata dependencies are not there just because
someone wanted to save time at boot ;)
