When creating a lobby, you can reserve certain slots for your friends! Just hit Advanced Settings, click the slots you want reserved and add your own password!

Like i do understand a mumble req lobby is not filling that fast against a non mumble req lobby. But point is the option is there and people are allowed to create a mumble req lobby. Only if it takes to long to fill and it is later already and it seems not to fill i will close it though
