Well, in d-i itself, the most important thing that comes to my mind
here is the created user real name.

And, when d-i installs packages from tasksel, we have merely any
package which inputs strings in its debconf screens.

So, in short, this issue has to be solved. We probably won't have time
to do it in beta2 and then we should document it in the errata file.
