FEC and Packet Duplication features in SD-WANs - worthwhile, or risky?

I'm curious to know if anyone here is currently leveraging FEC or packet duplication technologies in their SD-WAN environments today. On paper, it seems like an excellent idea to ensure that real-time applications get the appropriate treatment even over lower-quality transports. However, it was pointed out to me a while back (at least a year ago, perhaps two) that these technologies were buggy, not mature, and introduced a significant amount of latency. For those of you who have used or have tested these technologies today, do you agree with that assessment? Or are they absolutely worth considering when building out a new design?
