I concur, this seems like something to have. At the very least, an additional section on Special:BlockList listing the chat bans would suffice. I didn't even know there wasn't a separate list for chat bans until you brought it up.

This should be something you send in to Special:Contact/feedback, that'll definitely get it noticed.
