That's what would break.  Scripts have been written to assume that 'rm
empty_dir' will fail, and your proposal would change that assumption.
Falling through to subsequent commands when you used to bail out early
has all sorts of subtle implications, that we aren't willing to risk.

'set -e' is useless. I highly recommend that script writers avoid it.
