There could be benefits to having a shared implementation, but my gut says that it could also be more trouble than it's worth - although the debug adapter protocol is "generic", in practice it still seems to require some specialization per-debugger and per-client (from the small sample size I've observed), and I suspect the "Dexter version" might end up with significant deviations based on the needs of Dexter and the behaviour of other debug adapters. With that said, that's just my first impression - I'll take the time to compare the implementations in more detail later, since I agree it would simplify ongoing maintenance if the code could be shared.
