Thanks for your input on that subject.
After having seen with Alexey, we're about to reword the paragraph
as follows:

      Similarly, it is not recommended to use a "%s" pattern rule for
      the moderation submission template for two moderated newsgroups
      whose names differ only by the case of their characters, because
      email systems are frequently treating left-hand-side of email
      addresses as case-sensitive.

I hope it's fine for everyone.
