Electric indentation is more useful in a language like C than it is in
something like Python --- C has a richer set of brace characters.
cc-mode's sophisticated syntactic indentation is an Emacs "killer feature".

Anyway, we should be showcasing it by default, using electric
indentation, instead of hiding it behind configuration because users
might want to lobotomize their indentation by rebinding <tab>.
