Didn't racket also make the decision to make cons create immutable lists (and using mcons for mutable lists)?

But that's not what Clojure did. In clojure, cons cells aren't cons cells: they're a cell that can point to a sequence of some type, and contain a pointer to arbitrary data. They also do not make up lists, and have weird equality rules.

Racket's conses are merely immutable.
