The problem is that we're still using these ancient shells when we have better ones. Users shouldn't be wasting time memorizing arcana like "set -e". At least we have search engines now...
I'm quite partial to the fish shell myself for this reason.
But I SSH into a lot of embedded systems these days, where you don't exactly have the luxury of installing your own shell all the time. For those times I like to whip out the "minimal safe Bash template" and `sftp` it to the server.
