regular fsck runs are too disturbing

And that is where I completely disagree with you.  The reason journals 
were added to ext3 was to avoid the need to fsck after a dirty unmount. 
  If the fs does not need checked after a dirty unmount, why does it 
need checked after 30 clean mounts?  In practice, in my experience, 
modern journaling filesystems DO maintain integrity.  Also see the 
plethora of servers out there running ext3 with hundreds of days of 
uptime.  They NEVER run fsck because they are never rebooted, and they 
suffer no data loss.
