Wrong.
ALL Journaling FSes automatically replay the long upon mounting, or at
least i don't know of any that don't.
Only if there is additional corruption the corresponding fsck comes into
play.
For XFS i have only needed xfs_repair 1 time in over 10 years (and
countless power-failures/spontanous resets, forgotten umounts
(USB-drives) ...) and that was caused by a bug in XFS that was fixed
recently, otherwise my stat would still be 0.
In most cases, after an unclean shutdown, the journal is replayed and
everything is fine. Otherwise you either hit a bug (that needs fixing),
or you have hardware problems.
