The DAP doesn't really have a way to have multiple processes per debug session, but it does allow for multiple debug sessions in general. Compound launch configurations are one way to get this setup https://code.visualstudio.com/docs/debugtest/debugging-configuration#_compound-launch-configurations for example, you could have a server and a client in a compound launch configuration.

Cool, I knew we supported the request but I didn't know how that was hooked up. So it seems like this may be better supported than I thought. In that case we should definitely make sure we test that configuration and make sure it keeps working.
