Soft updates can not get around the full fsck problem. See my other posting under the title "Crash recovery", wherein I compare the crash recovery mechanisms, with special attention to the soft updates problem with abbreviated crash recovery. Soft updates does some good things, but it also does some bad things (at least relative to an LFS or JFS, and crash recovery).
