xeus-python vs ipykernel

[Saul Shanabrook]

In JupyterLab we are looking into adding support for a debugging protocol. To do this, we have to extend each kernel to support it.

I am trying to figure out if we should be putting resources into refactoring ipykernel to get it up to speed here or instead of just using xeus-python. I opened a Github issue about this on the debugger repo, and would appreciate any feedback folks had on there, especially from people who maintain these projects: https://github.com/jupyterlab/debugger/issues/274
