I don't think there are more than 100 Tremulous players still actively playing, so it's best to make the game friendly to newcomers instead of trying to appeal to old Tremulous players.
Today 2015-01-27, since 2014-12-12, my server has logged 591 connection from 114 unique nicknames from 33 country (I lost some logs from some hours but you get the idea). There was games each day on this server the two first weeks of january (and sometime all the day) so it seems this server had a good idea of the current playerbase.
Since some people had renamed themselves, you can think the current Unvanquished player base is about 100 people, so if there is no more 100 Tremulous players today, they are very precious, since newcomers can't come if there is no players to welcome them, and Tremulous players are the most likely to play Unvanquished.
