You can improve that situation somewhat by starting scripts with `set -o errexit -o noclobber -o nounset -o pipefail` and `shopt -s failglob` to fail fast.

Yes, this makes things better.

But then you will have to deal with the non-negligible amount of programs that use the exit value to return information. It is still better to place exceptions on failing code than to ignore errors that can wipe out your entire system, but it's not really good either way.
