I don't use them. But there are similar stupid features in bash which I also don't use. Configuring a shell seems normal to me.

I prefer not to configure much, the more I configure on my system, the harder it's to use another system (although, just using vim makes this hard on non-vim text editors.) Although I do find bash-completion handy in many situations (mainly for sub-commands), for mplayer it refuses to tab-complete videos not ending in a proper extension, which is rather annoying.

Don't get me wrong though, bash does have its bad points.
