The no-check TR language's bindings are not identical to TR in the transformer environment

What version of Racket are you using?

$ racket -v
Welcome to Racket v6.10.

What program did you run?

#lang racket

(module ok typed/racket
  (begin-for-syntax
    #'yep))


(module not-ok typed/racket/no-check
  (begin-for-syntax
    #'yep))


(module ok2 typed/racket/no-check
  (require (for-syntax racket/base))
  (begin-for-syntax
    #'yep))

What should have happened?

According to the documentation,

They provide the same bindings and syntax as typed/racket and typed/racket/base, but do no type checking.

where "They" refers to the no-check languages. Thus, the programs should all mean the same thing, and the for-syntax require of racket/base in the module ok2 should be redundant rather than necessary.
