No need to vote.. This can be done by players.
Except... It would be subject to the same limitations that other user-created channels suffer. It takes up one of the three spaces used for user-created channels, as does the Faction channel, any Civ channel, and any other channels one may be a member of. People already hop between multiple channels now because of limitations. When the server reboots, the channel no longer exists; anyone who had joined the channel will no longer automatically sign in.
And perhaps the most significant limitation, people wouldn't know it exists except via word-of-mouth. I realize some people have a very big mouth and are good at spreading messages, but new people will still need to know about it. And then they'll need to know how to join and how to leave. If you need to have a discussion about joining and leaving custom channels every time a new player asks about a group on Uni, that is worse spam than the looking-for-group requests now.
