Importing responses as ".library" is somewhat dangerous, yes. The libraries were never meant to be used that way. I have recently looked deeper into this, since the folks are MIT wanted to import a ".problem", and the namespace is a can of worms.

Yes, that's the namespace problem, it was never designed this way ...

Going in at the root level and extracting the information from the files would be fairly horrible, and one would lose anonymity. However, the latter can likely not be avoided anymore at this point. If the students still see their answers on the screen, I would suggest the following: switch the problem into regular homework mode, and make a detailed submission report. If that does not work, you might be able to get the information from the grading screen, by acting as if you want to regrade their submissions.
