It happens with paid subscriptions as well. Some examples of this, that I can think of: - Varnish Cache where you need a paid subscription, or community patches and you have to do the compilation yourself, to make it understand SRV-records instead of hardcoding IPs or hostnames. - Nginx also need a paid subscription to understand SRV-records. Both of these companies have realized that in order for people to effectively run the software within a cluster, you need support for SRV-records to get service discovery working.
