I agree with mink, and would actually be in favor of it disappearing myself.

BotServ is not needed for anything besides the "look, we have a kewlz0r bot in our channel!!" factor. People can't gain ops in registered channels just by joining them, so a BotServ bot does not protect your channel. ChanServ can accept a full range of commands via /msg, again making BotServ unneeded.
