If I may chime in on this - I completely stopped modding DCS, simply because it is too much of a chore to keep up with in the current situation. This of course includes realsitic comm solutions which I have used in the past. I love mods in any game that allow them, but only as long as I don´t feel like the associated maintenance becomes the defining part of the experience...
I would actually prefer an integrated system, which requires a less cumbersome setup process to get running, even if it means that updates may be coming at a slower rate. After some of the current milestones have been reached some time until or during 2018, who knows - progress on built-in comm systems might not be so slow by then. Didn´t ED say that they wanted to keep improving the platform?
If voice-comms becomes an integral part, the process of maintaining its functionality lies with the people who plan all the other cahnges within DCS, so actually adressing bugs also becomes an internal process which should make compatabillity issues between different versions of DCS and SRS a thing of the past, no?
