There is no such submodule, but

    (enter! (submod racket/unit compat))

does work, and incidentally, exposes the fact that xrepl doesn't show
a submodule path in its prompt, yet.  (I'm not sure how it would be
shown, btw, using the submod form is very verbose for a prompt.)

I'm not sure about these, but IIRC, there was a similar question about
doing the same in drr.
