Is this package public somewhere? I would like to try to reproduce if possible.

No. The code by default ends in the package namespace. You don't need to set
anything. You should be able to deactivate the namespaced evaluation with C-c
C-t C-s. This is primary use of this command right now. There is no C-c C-t C-a
anymore.

Works just as expected for me. Would it be possible for you to install the
development version of ESS?
