If by Racket you mean the #racket language, that's not really true. It is a Scheme and embraces (and encourages) the purity of modeling that's associated with that.
is just a corner of the Racket ecosystem. If anything underpins it, it's the idea of teaching computer programming and computer science research. For elegance it #:extra-constructor-name for (struct...); contracts, units, modules, collections, objects, mixins and packages (two types); and two syntaxes for Regex.
That's of course not to say that the Racketeer ethic doesn't favor elegant code. Only that language design is not ideologically bound to it.
