Comment 3 for bug 49524

The problem is not expert users; I certainly do not consider myself such, but I have removed and then later readded ubuntu-desktop on several occasions for very specific conflicts.

However, this warning is not for experts, but for novices to specifically warn them away from uninstalling it if they can help it. Experts will simply ignore the warning because they know what they're doing :)

As for details, I have only the ones from the thread I linked in my first post, which are not very detailed.
