fraid I don't know, I only came up with that possibility when asked to briefly look into what it would take to implement it in GCC, where I didn't think it would fit. I figured GDB had the full-program context it would take, unlike GCC, that sees one translation unit at a time, and that was the extent of my involvement. if anything came out of it, I probably wasn't told, but if I was, I forgot. FWIW, I haven't ever interacted with a language server, this was all an exercise of imagination many years ago.
