Not formally. I'm heavily using it for kernel debugging for a couple of
years. Therefore, I'm fixing and enhancing it from time to time.

A good general rule, not only in open source, is to at least try to fix
existing infrastructure. If that fails provably, you can come up with a
new version to replace or augment things.
E.g., you didn't explain yet why the gdb protocol and our existing stub
cannot be extended in a backward compatible way that allows your
debugger to attach to it. That way not only your debugger (is it Windows
hosted?) could benefit from the improvements but the whole (x86) gdb world.
