Taking kafka-plugin on support

On this page https://gatling.io/docs/2.3/extensions/ it was mentioned that if there is demand, this plugin https://github.com/mnogu/gatling-kafka will be taken on support. So my question is, how do you track whether there is necessity in this functionality? Is there any voting or any other place where I can mention, that functionality would be very useful?
Thanks a lot in advance.
