The problem is that if the fsck finds something, you need to spend time on
it, watching the report, and you may need to answer questions with y/n for
it to proceed.

Sure, hardware damage that corrupts the file system in a place where
it isn't recognised at run-time. Only a periodic fsck will detect
that. And hopefully it doesn't come too late.

Depending on your partitioning scheme, it would be possible to keep the
automatic fsck intervals for your "small" system partitions (and tune them
so they are not checked at once) and run a shell script for checking
huge data partitions during shutdown (aftering unmounting them in the
script).
