Will therefore GDB utilize C++ or not?

The more things we add to gdbserver, the less I think it meets the
goal of "simple, light-weight target agent". I resisted code sharing
with GDB for a long time. If the consensus nowadays is that code
sharing is the way to go, then I think it behooves someone to figure
out the needs of a modern light-weight target agent that's a lot
smaller than gdbserver.
Yes, multiprocess debugging with gdbserver is an awesome development.
No, you don't need it in the stage of system bringup where you don't
have C++, if you're planning to have C++ eventually. So I think
there's room for a potential C++ gdbserver and a small C gdbserver.
How did I end up being the curmudgeon? I'm confused.
