I agree that language server and debugger are different beasts, but both LSP and DAP serve a purpose of re-using the same server (xrefs or debugger) with different IDEs.

> I can implement the LSP and get support for IDEs essentially for free I mean, technically same is true for DAP... You can implement DAP and get support for IDE for free. But I agree that in general case implementing a good debugger is harder than implementing a good language server.

If Drustzig requires a special debugger (e.g. because it uses acustom format of debug information), then you'd need to implement it, yes. However, existing debuggers can support new languages relatively easy if those follow standard conventions (e.g. use PDB and DWARF). For example, Rust support in LLDB basically comes down to a custom demangler.

Again, I'm not saying that DAP is perfect and solves debugging, but IMO it's a step in the right direction. Make it popular, make it extensible. Debuggers can be mostly language agnostic (within reasonable bounds), but they don't _have_ to be.
