Maybe using a reverb mod could be used as workaround, meaning if reverb is generally applied as an effect on all sounds occurring instead of replacing ingame sounds (so future sounds implemented in the game by Bohemia would still be processed by the effect without further needs for the addon update).
I've heard some good reverbs for arma 3, check Enhanced Soundscape from Laxemann.
