Actually there is something conclusive in this discussion:
https://lists.ubuntu.com/archives/ubuntu-devel-
discuss/2007-December/002764.html

"To try to answer the question of whether we could simply disable the
periodic fsck, I decided to ask Mingming Cao, one of the developers
who has worked on ext3 and later, ext4.  I just got the following:

"Periodically fsck ext3 is still needed, even if ext3 is a journalled fs.
kernel code vm/fs could be buggy, or disks IO errors, which cause
filesystem metadata corrupted silently, this can't be detected by simply
replaying the journal log.

[....]"

That must go doubly for removable disks, due to more likely unclean
removal and additional risk of hardware issues (disks being carried
around, etc.)

And here Martin Pitt mentions a UDS decision about how to deal with fsck
for fixed disks: https://lists.ubuntu.com/archives/ubuntu-devel-
