For the DAP side (the @request) this is arguable but also fine.
I personally think it's clearer to only name parameters that are
actually used, but if you want to do it that way, I'll approve it.

On the gdb side (@in_gdb_thread) I think it's better to only accept
things that are actually used.  It's also arguably better here to do any
needed pre-processing in the DAP thread.
